Alabama running back Jam Miller is in concussion protocol and is questionable for Saturday night’s Southeastern Conference showdown between the No. 6 Crimson Tide and No. 11 Tennessee in Tuscaloosa.

Head coach Kalen DeBoer confirmed Wednesday that Miller sustained the injury late in last weekend’s 27-24 win at then-No. 14 Missouri.

Miller has rushed 58 times for 267 yards and one touchdown in three games this season. The senior was sidelined for Alabama’s first three games after breaking his collarbone during fall camp.

Over four seasons with the Crimson Tide, Miller has gained 1,638 yards from scrimmage with 13 touchdowns in 43 games.

If Miller can’t go, Kevin Riley (183 yards) and AK Dear (85 yards) likely will see more action when Alabama (5-1, 3-0 SEC) and Tennessee (5-1, 2-1) meet.
