Miguel Tejada of Kansas City Royals suspended for 105 games

Updated at 3:47 p.m. ET

KANSAS CITY, Mo. Former MVP Miguel Tejada was suspended for 105 games on Saturday for testing positive for an amphetamine, one of the longest suspensions given by Major League Baseball.

The 39-year-old infielder for the Kansas City Royals is already on the 60-day disabled list. He is not challenging the penalties and will begin serving the ban immediately.

"I apologize to my teammates, the Royals organization and to the Kansas City fans," Tejada said in a statement released by the players' union, the Major League Baseball Players Association.

Tejada previously tested positive under the league's amphetamine policy. That subjected him to a 25-game ban for a second test and an 80-game suspension for a third, both of which occurred while playing for the Royals this season.

A person familiar with the situation told The Associated Press that Tejada tested positive for Adderall, a substance that he had previously used to treat attention-deficit disorder. The person spoke to the AP on condition of anonymity because those details were not made public.

MLB's medical staff occasionally grants therapeutic-use exemptions that allow players to use drugs such as Adderall to treat ADD and other disorders. However, Tejada no longer had the proper authorization to use the drug and the positive tests warranted a suspension.

In his statement, Tejada referred to a "medical condition" he has that requires him to take medication.

"I took that medication while re-applying for a Therapeutic Use Exemption," said Tejada. "Under the requirements of the Joint Drug Program, I made a mistake in doing so."

Saturday's announcement comes on the heels of last week's 211-game suspension that the league announced against New York Yankees star Alex Rodriguez.

On Friday, CBS' "60 Minutes" reported that members of Rodriguez's inner circle in February obtained and leaked documents that implicated Milwaukee Brewers slugger Ryan Braun as well as his own Yankees teammate, catcher Francisco Cervelli, in the doping scandal.

Rodriguez said the "60 Minutes" report isn't true. He is also appealing the league's suspension.

Tejada's suspension is the third-longest non-lifetime ban handed down by MLB behind Rodriguez's and reliever Steve Howe's 119-day penalty in 1992.

Tejada, who signed a one-year deal with the Royals last offseason, is on the disabled list with a strained calf. He would need to fulfill the remainder of the suspension next season before he's eligible to play.

A six-time All-Star who won the AL MVP award in 2002, Tejada has been dogged by doping allegations throughout his career. The first significant mention of his name came in the Mitchell Report on steroids use in baseball. Then in February 2009, Tejada was charged with lying to Congress about performance-enhancing drugs in the game. He pleaded guilty to the charge and received one year of probation.

Tejada spent last season out of the big leagues after struggling two years ago with the San Francisco Giants. He wound up signing a deal with the Royals in December, and was hitting .288 with three homers and 20 RBIs in 53 games before getting hurt.
