Jacksonville Jaguars running back Rashad Jennings has not passed his concussion test and will miss practice on Wednesday, according to head coach Mike Mularkey. Jennings suffered the concussion during Week 13's loss to the Buffalo Bills.

Prior to the injury, Jennings had run for 283 yards and scored two touchdowns. He has also caught 19 passes for 130 yards this season, but has also lost one fumble this year while fumbling three separate times. His most productive game this season has come in Week 9 against the Green Bay Packers, during which he ran for 59 yards on 17 carries in addition to six catches for 56 yards.

The Jaguars now are preparing for this Sunday's game against the Miami Dolphins at Sun Life Stadium. The game is scheduled for a 1 p.m. kickoff and the game will be broadcast on CBS with radio coverage on WOKV 690 AM and 106.5 FM.
