The 25-year-old nose tackle played 266 snaps between the Falcons and Titans last season. It was the most work he has seen in his three-year career. A pure run stuffer, Rush still has some room to grow on early downs, but those kinds of players don't usually graduate beyond the 400-500 snap range. 

Rush was signed off the Raiders' practice squad earlier this week, but he originally signed with the Eagles after going undrafted out of UAB in April before waived over the summer. The 23-year-old should see a sizable role as he makes his NFL debut Sunday at Buffalo, with Tim Jernigan (foot) missing the last five games and with Hassan Ridgeway (ankle) and Malik Jackson (foot) on injured reserve. The only other healthy defensive tackle on the roster besides All-Pro Fletcher Cox is another undrafted rookie in Albert Huggins, who was also signed this week.

Rush was signed from the Raiders' practice squad as the Eagles parted ways with veteran defensive tackle Akeem Spence. An undrafted rookie, Rush was a standout during the Raiders preseason and has spent the entire season on the practice squad.
