Sims (knee) returned to practice Wednesday, opening his 21-day window for activation from injured reserve, Scott Smith of the Buccaneers' official site reports.
Sims was always the most logical of Tampa Bay's IR members to make another appearance this season, but when (or if) he does, he'll take on his normal change-of-pace role behind Doug Martin. In four games this season, Sims offset 2.8 yards per carry with 14 receptions (on 19 targets) for 112 yards. His first opportunity to play again will be Dec. 11 against the Saints.
