West Virginia and Arizona enter Saturday’s game at Tucson, Ariz., with significant injury concerns and disgruntled fan bases over their performances this season.It will be the first meeting between the football programs. Both are now in the expanded Big 12.West Virginia (3-4, 2-2) was uncertain early this week about the status of starting quarterback Garrett Greene, who did not play because of an upper-body injury in the second half of last week’s 45-18 home loss to then-No. 17 Kansas State.If Greene can’t play, Chandler, Ariz., native Nicco Marchiol will take over.”(Marchiol) is going to get a bunch of reps, so if his number’s called, he’ll be ready, and I expect him to play at a high level,” West Virginia coach Neal Brown said.Arizona (3-4, 1-3) will be without linebacker Jacob Manu, one of the team’s captains, and offensive tackle Rhino Tapa’atoutai for the rest of the season.Manu suffered a non-contact knee injury and Tapa’atoutai a leg injury in a 34-7 home loss to Colorado last week.
