Injuries to quarterbacks at several non-AQ schools have started to mount. Here is a primer:
Injured: Case Keenum has mild concussion symptoms after getting hurt following an interception he threw against UTEP last week. His status is day-to-day.
Who's in: If Keenum can't play against UCLA on Saturday, Cotton Turner would get the nod. Turner went 9-of-10 for 69 yards with a touchdown in relief of Keenum against UTEP. "Our players, when he hit the field, there’s a confidence level in him and Friday night can only help everybody’s confidence level in him," coach Kevin Sumlin said.
Who's injured: Cannon Smith sustained a concussion against East Carolina and is out for this week's game against Middle Tennessee.
Who's in: Ryan Williams, a true freshman, played well in relief of Smith last week, going 18-of-25 for 293 yards and three TDs. Williams has played in both games this season.
Who's injured: The Blue Raiders are actually down to their third quarterback, following the suspension of starter Dwight Dasher. Logan Kilgore, who replaced him, missed last week's game against Austin Peay with a toe injury and is still in a walking boot.
Who's in: Jeff Murphy started last week and went 23-of-36 for 301 yards with no touchdowns and an interception. Both he and Kilgore are junior college transfers playing their first season at Middle Tennessee.
Who's injured: Nathan Tune dislocated his hip in a loss to Rice, and is expected to miss the rest of the season.
Who's in: Derek Thompson. He has played sporadically and doesn't have much experience, but there isn't much depth here. Riley Dodge, the starter last season, moved to receiver because of elbow troubles but will go back to quarterback to help with depth.
Who's injured: Taylor McHargue sustained a mild shoulder separation against North Texas last week and is out for Saturday's game against Northwestern.
Who's in: Nick Fanuzzi, who started last season but lost his job to McHargue in the fall. Fanuzzi came in against the Mean Green and led the game-winning drive in the fourth quarter and finished 12-for-23 for 189 yards and a touchdown.
Injured: Jordan Wynn sprained the thumb on his throwing hand in the season opener against Pittsburgh and is listed as day to day. He missed last week's game against UNLV and his status is unclear for Saturday's game at New Mexico.
Who's in: Terrance Cain. He is a capable player, having started eight games last season. Against UNLV, Cain went 13-of-20 for 207 yards with two touchdown passes. "We’re fortunate to have Terrance Cain as our backup," coach Kyle Whittingham said. "We had no panic, no concern because we knew Terrance was going to step in and get the job done."
