Jackson has missed two practices this week due to illness yet is expected to play on Sunday. The veteran back has 909 yards rushing and three touchdowns in 14 games this season.
Cornerback Cortland Finnegan is doubtful for Sunday's game after not practicing while dealing with a thigh injury. Finnegan had a forced fumble in Week 15 against the Vikings and has three interceptions on the season.
Linebacker James Laurinaitis (back), cornerback Bradley Fletcher (illness), defensive end Robert Quin (illness) and center Scott Wells (knee) are also listed as probable.
The Rams are currently still mathematically in the playoff hunt with a 6-7-1 record, but a win any win from the group of Minnesota, Chicago, Dallas and the New York Giants will mean the Rams are eliminated from postseason contention.
