Maryland’s defensive line may look a little thinner come the fall.

Thursday, Jeff Ermann of InsideMDSports reported that expected starting defensive lineman Adam McLean has thrown his name into the NCAA transfer portal. He will explore opportunities to play elsewhere, despite the opportunity to make a significant impact for the Terrapins this fall.

There were not any details on what prompted McLean to explore other opportunities at the time of the report. The defensive lineman is entering his senior year, meaning he will have just one year of eligibility remaining. Because he has not yet graduated, McLean would not be eligible to compete in 2019 should he land at another FBS program.

McLean started in 11 games for the Terrapins last season, making 36 tackles and one sack. He also saw action in 2017, appearing in nine games and registering 11 stops.

New NCAA transfer portal rules allow players to explore other opportunities outside of their current school, but McLean can still return to Maryland if that’s in his best interest. There was no mention of a potential landing spot for the defensive lineman.

The Terrapins open the 2019 season at home against Howard on Saturday, Aug. 31.
