Tampa Bay Buccaneers cornerback Eric Wright faces a four-game suspension for using Adderall, Fox Sports reported Sunday.
Adderall use violates the NFL's policy on performance-enhancing drugs. The league has not announced any discipline for Wright.
Some players reportedly take the drug to deal with attention deficit disorder.
The Buccaneers already lost cornerback Aqib Talib for four games for testing positive for Adderall.
If Wright is suspended, Brandon McDonald and Myron Lewis are contenders to replace him.
