GuardsRajon Rondo, PG (BOS)--The Celtics received horrible news prior to Sunday's game involving their All-Star point guard. Rajon Rondo will likely miss the rest of the season with a torn right ACL, which came on a drive to the hoop on Friday night, so owners should drop him now and find a replacement.Klay Thompson, SG (GS)--It appears the Warriors may be without their starting shooting guard when they take on the Raptors on Monday as he battles an illness. Klay Thompson missed practice on Sunday due to the illness, so owners should check prior to game-time to see if he is active.Chris Paul, PG (LAC)--The Clippers have been without Chris Paul for four straight games as he continues to deal with a bruised knee. The team is being very cautious with the injury to prevent further damage, so don't expect to see him back in the lineup this week.Mike Conley, PG (MEM)--The Grizzlies are considering Mike Conley questionable for Monday's game against the Sixers after twisting him ankle in Sunday's game. With four games slated for this week it will be hard to bench him, but there has been no more news on the injury just yet to determine how long, if at all, he will be out of action.Alexey Shved, SG (MIN)--Although Shved has been out for five straight games, there is a chance he returns for Wednesday's game against the Clippers. The Timberwolves have been hit hard with injuries and a return from Shved this week would be nice to see for both fantasy owners and the team, but until official word is released, he must be left on the bench.Jason Richardson, SG (PHI)--The Sixers consider Jason Richardson questionable for Monday's game against the Grizzlies as he continues to deal with a knee injury. After missing three straight games, the injury may be more serious than originally reported, so owners should keep him benched until further news is released.Kyle Lowry, PG (TOR)--There is a chance the Raptors will be without Kyle Lowry for Monday's game against the Warriors while he battles back spasms. Lowry has been banged up for most of the season, and is now coming off the bench, so if he misses time this week, it won't be that big of a deal.Gordon Hayward, SG (UTA)--After suffering a shoulder injury, there is a chance the Jazz will be without the services of Gordon Heyward for Monday's game against the Rockets. He suffered the injury in Saturday's win over the Pacers, but it does not appear to be serious at this time.Steve Blake, PG (LAL)–The Lakers expect to have backup point guard Steve Blake back in action sometime on Tuesday for the first time since the early stages of the season after undergoing successful surgery to repair a torn abdominal muscle. He is expected to come off the bench as Steve Nash's backup, which will limit his fantasy potential. Chauncey Billups, PG (LAC)–The Clippers have yet to set a timetable for Chauncey Billups’ return to action after he sustained a foot injury over a month ago. The injury is considered peroneal tendinitis, which will require therapy, so in weekly leagues it would be wise to avoid him until more news is released on the extent of the injury.Mo Williams, PG (UTA)–After suffering a thumb injury, the Jazz don’t expect to have Mo Williams back in their lineup until at least late February. The injury has become more serious than originally expected, and now that Williams will be out for at least one more month, Jamaal Tinsley’s fantasy value has now increased.Derrick Rose, PG (CHI)–The Bulls continue to be cautious with Derrick Rose while be continues to rehab from knee surgery, but they expect to have him back for the second half of the season. After the All-Star break is probably a good guess for when he will return to action, so those in daily lineup leagues should consider stashing him now if he is available. Brandon Roy, SG (MIN)–The Timberwolves had Brandon Roy back in practice the last few weeks, but have yet to determine a return to action. Roy underwent knee surgery back in November and will need to go through a vigorous rehab to return to action.ForwardsLuol Deng, SF (CHI)--The Bulls consider Luol Deng questionable for Monday's game against the Bobcats as he continues to deal with a hamstring injury. Deng has now missed the team's last five games, but it appears a return is near as he continues to add to his pregame workouts.C.J. Miles, SF (CLE)--The Cavaliers consider C.J. Miles questionable for Tuesday's game against the Warriors as he continues to deal with a lingering illness. Miles has missed three straight games with the illness and it does not appear to be getting better, so it may be wise to bench him this week.Gerald Green, SF (IND)--Like many others around the league, Gerald Green has come down with an illness that may force him out of the Pacers lineup on Monday. He has missed the last two games with the same symptoms, and the team is already considering him doubtful for their next game.Tim Duncan, PF (SA)--The Spurs are being cautious with Tim Duncan's knee injury, and have listed him as questionable for Wednesday's game against the Bobcats. Duncan missed the team's last game with the same injury, and with only two games this week, those in weekly leagues should bench him with the thought he won't play in Week 14.Hedo Turkoglu, SF (ORL)–The Magic consider Hedo Turkoglu Doubtful for Monday’s game against the Nets as he continues to deal with a hand injury. Turkoglu has missed the last few weeks with the injury, but prior to missing time, he wasn’t much of a fantasy contributor.Kevin Love, PF (MIN)–The Timberwolves may be without Kevin Love until mid-March  after an MRI revealed he re-fractured abone in his right hand. Love missed the start of the season with the same injury, which is never a good thing when deal hand injuries.Andrea Bargnani, PF (TOR)–After suffering a torn elbow ligament, the Raptors don’t expect to have Andrea Bargnani back in action until late January. Although that timetable may be a bit loose, more information will have to surface before giving any advice on his availability.Danny Granger, SF (IND)–It appears that Danny Granger will be back in action for the Pacers by early February after missing the first half of the season with a knee injury. The Pacers are playing well without him, so it will be interesting to see just how he fits back into the rotation once healthy.CentersNikola Pekovic, C (MIN)--The Timberwolves could see Nikola Pekovic return to action for Wednesday's game against the Clippers, but no official word has been released at this time. Pekovic has missed the team's last five games with a quadriceps injury, but it does not appear to be too serious.Anderson Varejao, C (CLE)–The Cavaliers expect to have Anderson Varajao back in their lineup at some point in March once he fully recovers from knee surgery. The team announced in early-January that the surgery was successful and that he is expected to miss 6-8 weeks.Jonas Valanciunas, C (TOR)–The Raptors will be without the services of Jonas Valanciunas until at least late-January after suffering a finger injury. He has shown flashes of fantasy value in his rookie season, so hopefully this injury will not set him back too much once he returns.Andrew Bogut, C (GS)–The Warriors expect to have Andrew Bgut back on the court relatively soon, considering he the team stated he is “coming along really well.” Bogut has yet to pay this season after suffering ankle injury and will have a big role int he Warriors offense once he returns to action. Andrew Bynum, C (PHI)–The Sixers will be without Andrew Bynum until at least early-February as he continues to battle back from a knee injury. Bynum has yet to play this season, but when he returns, he should be a solid fantasy contributor in most categories, so if he is available now is the time to pick him up. Byron Mullens, C (CHA)–After suffering an ankle injury over a month ago, the team is now considering Bryon Mullens out until at least early February. Mullens has taken a step forward in is progression as a starting center, so hopeful this injury will not set him back once he returns.
