Tampa (CBS) According to multiple sources, Buccaneers cornerback Aqib Talib has been suspended for violating the NFL’s policy against performance enhancing drugs. Talib, arguably the Bucs best defensive back, will miss four games, starting with this week’s home game against Kansas City.

Talib says the suspension was due to his use of Adderall without a prescription. In a statement released byt the Bucs, Talib said, “Around the beginning of training camp, I made a mistake by taking an Adderall pill without a prescription. This is especially regrettable because, for the past several months, with Coach Schiano’s help, I’ve worked very hard to improve myself — professionally and personally — as a player and a man. I am truly sorry to my teammates, coaches and Buccaneers fans, and I’m disappointed in myself. I will work diligently every day of this suspension to stay in top football shape and be ready to help this team in the second half of the season. I have chosen to be immediately accountable for the situation I put myself in, which is why I will not exercise my appeal rights and will begin serving the suspension immediately.”

Head coach Greg Schiano said, “We are disappointed to learn that Aqib Talib will be suspended for four games which will begin with our game tomorrow against Kansas City. I have spoken with Aqib, and he knows and he knows that he made a poor decision that let our team down. Certainly, other players will have the opportunity to step up while he serves this suspension.”

A lightning rod for controversy throughout his career, Talib is in his 5th seasosn with the Bucs. He will be eligible to rejoin the team for it’s game against the San Diego Chargers on November 11th.
