Travis Frederick

Frederick just turned 29 years old last week, so this comes as quite a surprise. Frederick, of course, missed the entire 2018 season as he battled Guillain-Barre Syndrome, but he returned to the field last year and started all 16 games on his way to a Pro Bowl. Frederick says in his announcement that while he played "well," he didn't play at the standards he felt he was at before missing 2018 and cites numerous reasons for stepping away. In his six healthy seasons, Frederick never missed a start and made the Pro Bowl five times with one first-team All-Pro selection. The Cowboys will now move forward with Joe Looney penciled in at center for the time being. Looney started for Frederick in 2018.

He's still being held out of one-on-one drills, largely due to offseason shoulder surgery, but this is a huge step forward in the center's recovery from the autoimmune disorder. Frederick remains on track to start in Week 1 and help the Dallas offensive line return to the dominant form it lost while he was sidelined last season.

Frederick sat out the entire 2018 season after being diagnosed with Guillain-Barre syndrome. Prior to the setback, he landed four straight Pro Bowl bids and was considered one of the best centers in the game. It's unclear where his overall game is after dealing with a serious health scare, but the 28-year-old's availability for 2019 is certainly a feel-good start to camp for him and the Cowboys' organization.

After missing all of 2018 while battling Guillain-Barre syndrome and undergoing minor shoulder surgery this offseason, it was expected that Frederick would be held out of team drills and full practices until at least training camp. It's still an encouraging sign that he's able to handle individual drills already, however. The Cowboys' offensive line took a step backwards in effectiveness last year without its starting center, so if Frederick is able to return to anything close to his prior form, it will provide a boost for the entire offense.
