FARGO, N.D. (AP) — North Dakota State starting defensive tackle Leevon Perry is done for the season after suffering a left knee injury in NDSU's win over South Dakota State on Saturday.

Bison coach Craig Bohl says the injury to the 6-foot-3, 276-pound junior from Cottage Grove, Minn., is "significant" but hopefully not career-ending.

The No. 1 ranked and defending national champion Bison (9-1) play at No. 11 Illinois State (8-2) on Saturday.
