Arkansas' Knile Davis is back after missing 2011 with an ankle injury.
Injuries are a big part of any college football season. 2011 was no different, as losing Knile Davis was a key setback to Arkansas' hopes of winning the SEC West last year, while Missouri's offensive line had to shuffle some players around after Elvis Fisher was lost for the year with a knee injury.
Although those players were missed in 2011, their return to the gridiron is an even bigger storyline for 2012.
