There is a dark cloud hanging over the Hawaii football program entering Saturday’s game against Tulane, and it has nothing to do with its three-game losing streak.

The game between Hawaii (5-6) and Tulane (2-10) at Aloha Stadium takes place four days after news broke of an alleged point-shaving scandal involving Hawaii football players. An anonymous letter making the claims was sent to the school’s admissions office Nov. 3.

Hawaii coach Greg McMackin and school officials haven’t commented on the allegations. Honolulu police say there’s not enough information to open a criminal investigation.

Hawaii needs to beat Tulane and visiting BYU on Dec. 3 to qualify for the Dec. 24 Hawaii Bowl.

Hawaii will start David Graves at quarterback for the first time this season Saturday.
