Arizona Wildcats starting quarterback Matt Scott is considered doubtful to play Saturday against visiting Colorado, according to the team’s official injury report.
Scott suffered a concussion last Saturday at UCLA. His likely absence clears the way for junior college transfer quarterback B.J. Denker to start vs. the Buffaloes (11:30 a.m., FX). His backup will be receiver Richard Morrison, who worked at the position through spring and a bit of fall camp.
Two other starters are also doubtful while recovering from concussions — free safety Jourdon Grandon and offensive guard Chris Putton. Each has started every game this season.
Putton has started at both guard spots, also playing left tackle during games. Arizona can use a combination of Shane Zink, Trace Biskin (who recently returned from a toe injury), true freshman Cayman Bundage and Addison Bachman at guard.
Bachman has started the past four games at center, but can slide to guard now that Kyle Quinn is back.
Grandon’s backup on the depth chart is walk-on freshman Vince Miles, although the coaching staff can mix and match its safety combinations.
Elsewhere on the depth chart:
–Defensive lineman Kirifi Taula, who has missed the past three games because of a shoulder injury, has been upgraded to probable.
–Fullback/defensive end Taimi Tutogi, who did not play last week because of a neck injury suffered in practice, is questionable.
–Linebacker Hank Hobson, who has hospitalized last Saturday night in Los Angeles after collapsing on the field, is out because of a neck injury.
Continuing to be out are starting defensive end Dominique Austin (foot) and starting wide receiver Terrence Miller (ankle).
