During the offseason, there was some concern Aqib Talib would wind up being suspended by the NFL for violating the personal conduct policy as he faced criminal charges in Texas.

That matter was cleared up but now Talib must serve a four-game suspension for violating the NFL’s policy on performance enhancing substances. Talib’s suspension begins immediately meaning he will not play Sunday when the Bucs host the Kansas City Chiefs. The veteran cornerback will be eligible to return to the team’s active roster on Nov. 5.

“Around the beginning of training camp, I made a mistake by taking an Adderall pill without a prescription,” Talib said in a statement released by the club. “This is especially regrettable because, for the past several months, with Coach (Greg) 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.”

Schiano said that he is disappointed.

“I have spoken with Aqib, and he knows that he made a poor decision that let our team down,” Schiano said. “Certainly, other players will have the opportunity to step up while he serves this suspension."
