Baltimore Orioles' first baseman Chris Davis has been handed a 25-game suspension after being found guilty of taking a banned substance.
The 28-year-old tested positive for an amphetamine and will miss the remainder of the Orioles' regular season after Major League Baseball (MLB) issued the sanction on Friday.
Baltimore are currently top of the American League East with an 86-59 record, and look set to win that section and advance to the post-season.
Davis will be unavailable for their 17 remaining regular-season games, and as many as eight games in the play-offs.
"Orioles first baseman Chris Davis received a 25-game suspension without pay on Friday after testing positive for an amphetamine in violation of Major League Baseball's Joint Drug Prevention and Treatment Program," said a brief statement from MLB.
"The suspension is effective immediately. The 25 games shall include all regular-season games and post-season games in which Davis would have been eligible to play."
Davis expressed his sorrow and readily agreed to the punishment.
"I apologise to my teammates, coaches, the Orioles organisation and especially the fans," he said.
"I made a mistake by taking [the amphetamine] Adderall. I had permission to use it in the past, but do not have a therapeutic use exemption (TUE) this year.
"I accept my punishment and will begin serving my suspension immediately."
