Fox Sports Insider and NFL Network contributor Jay Glazer reported Sunday that Bucs cornerback Eric Wright faces a similar four-game ban for using the same substance, which violates the NFL's policy on performance-enhancing drugs.
The NFL has yet to announce an official punishment for Wright, but losing the sixth-year veteran would further weaken Tampa Bay's secondary on a defense that ranks 31st against the pass.
We've seen a rash of Adderall-related suspensions this season, and Glazer emphasized that some players take the drug to cope with attention deficit disorder.
If Wright is lost, cornerbacks Brandon McDonald and Myron Lewis will see increased snaps across from E.J. Biggers, who has stepped in for the exiled Talib. It's a headache this young team could do without.
