For the second time in Jim McElwain’s tenure as a head coach, he’s lost a quarterback to a suspension for a banned substance.

Central Michigan quarterback David Moore has tested positive for a banned substance and has been suspended by the NCAA, according to Central Michigan Life.

While Central Michigan did not deny Moore’s positive test, it cited the use of an over-the-counter nutritional supplement as the likely cause. The university announced it plans to appeal the NCAA’s decision. Moore is ineligible to play through the appeal process.

When McElwain was at Florida, QB Will Grier accepted an NCAA suspension for using a banned performance-enhancing supplement in October 2015. At the time, he had led Gators to a 6-0 record as a redshirt freshman. McElwain said then that it was “an honest mistake” by Grier, who said he “took an over-the-counter supplement that had something in it,” FOX Sports’ Bruce Feldman reported.

According to the NCAA, the penalty for a positive test of a performance-enhancing drug is automatic. If the ruling is upheld, Moore will lose one full year of eligibility and will be withheld from competition for 365 days from the date of the test. For a second positive test of a banned substance, the quarterback would lose all remaining eligibility.

Central Michigan Athletic Director Michael Alford met with Moore and football coach Jim McElwain. He announced the decision to appeal the NCAA’s ruling.

“The university partners with the NCAA to ensure its student-athletes play by the rules and exhibit the highest level of conduct,” Alford said in a press release. “Based on the university’s review of the available evidence, the university has decided to appeal this ruling.”

Moore came to Central Michigan from Garden City Community College, where he played the 2018 season after transferring from Memphis. He’s completed 94-of-164 passes for 1,143 yards, five touchdowns and four interceptions.
