Expectations for Citadel football next season are as high as they’ve been in years, thanks to last year’s 7-4 mark and wins over FCS powers Georgia Southern and Appalachian State.

But the Bulldogs may have to meet those expectations without their lone All-American, center Mike Sellers.

Sellers, a rising senior and three-year starter, did not participate in Friday’s opening session of spring practice. An athletic department source said Sunday that Sellers ran afoul of the military school’s honor code, accused of an academic honors violation.

There is an appeals process for honor violations, but it was not clear Sunday if Sellers would appeal.

Coach Kevin Higgins could not comment, and Sellers could not be reached for comment.

Sellers, 6-0 and 290 pounds, came to The Citadel from Fort Dorchester High School as a fullback and defensive lineman. The Bulldogs moved him to center and made him a starter as a freshman.

After early struggles, he blossomed into an all-Southern Conference and then FCS All-American performer, winning the SoCon’s Jacobs Blocking Trophy last season.

If Sellers cannot play for The Citadel next season, rising sophomore Sam Frye (5-10, 270) is the likely starter after serving as Sellers’ backup last season.

Sellers could transfer to another school to finish out his eligibility, as did former Citadel running back Asheton Jordan (at South Carolina State) and basketball player John Brown (who became an all-Big South forward at Liberty).
