Oregon's Noah Whittington a game-time decision vs. Indiana - ESPN

ATLANTA — Oregon leading rusher Noah Whittington is expected to be a game-time decision for the College Football Playoff semifinal against Indiana Friday night, sources told ESPN.

Whittington unexpectedly showed up on the Oregon injury report on Thursday and was listed as questionable. He's dealing with an undisclosed injury and is expected to warm up in an attempt to play.

This development comes at a position where Oregon is dealing with significant depth issues, as the Ducks are already without Jordon Davision, the second leading rusher, who is out with an upper body injury.

Oregon's actions this week appear to underscore the concern at the position. ESPN's Katie George reported earlier Friday that the Ducks moved two defensive players to tailback — safety Kilohana Haasenritter and linebacker Brayden Pratt. (Haasenritter began his career as a tailback before moving to safety this fall.)

If Whittington can't go, Oregon would lean on freshman Dierre Hill Jr., who has 570 yards on 70 carries.

Oregon's fourth leading rusher, Jayden Limar, is in the transfer portal and not with the team. That leaves six-leading rusher Jay Harris — quarterback Dante Moore is the fifth — as a main option for the Ducks. Harris is also in the portal, but he remains with the team. He has 116 yards on 26 carries.

A decision on Whittington is expected to be made after warm-ups.
