The NFL suspended Tampa Bay Buccaneers cornerback Aqib Talib four games on Saturday for using Adderall, which is on the league's banned substances list, reports ESPN.com.

Adderall is commonly used for the treatment of attention deficit hyperactivity disorder and narcolepsy, a chronic sleeping disorder.

Talib will start his suspension Sunday when the Bucs play the Kansas City Chiefs. Talib does not plan to appeal his suspension. The team promoted defensive end Markus White from the team's practice squad to the active roster.

"Around the beginning of training camp, I made a mistake by taking an Adderall pill without a prescription," a statement from Talib read. "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."
