The three Clemson players that reportedly failed a drug test in the days before the team’s appearance in the Cotton Bowl are unlikely to participate in the College Football Playoff semifinal game on Saturday.

Pat Forde and Pete Thamel of Yahoo! Sports reported that the NCAA is awaiting “B” sample results from Dexter Lawrence, Zach Giellan and Braden Galloway, which could potentially clear the three players to participate in Saturday’s contest. However, the report says that the likelihood that the “B” sample clears the players are “slim to none.”

The three Tigers were suspended after testing positive for a “sliver of ostarine,” which has been used to help recover from injury.

Clemson head coach Dabo Swinney made the announcement that the three players failed the drug test on Christmas Eve. Lawrence is the most significant name among the bunch, as he’s been a star along the Tigers’ defensive line.

While there’s a chance the three players could be eligible to play against Notre Dame on Saturday, the odds aren’t that great.
