1:25pm: Bob Nightengale of USA Today tweets that Tejada did file an appeal, but he ultimately lost and will serve the entirety of the 105-game ban.
12:56pm: Royals infielder Miguel Tejada will be suspended for 105 games by MLB for the use of the banned amphetamine Adderall, Jeff Passan of Yahoo Sports reports. Passan explains that, as Tejada had already tested positive in the past, two more recent positive tests provided the basis for the suspension, which is the third-longest in MLB history. (The second positive test resulted in a 25-game ban, with the third adding an additional 80 games.)
Tejada has elected not to appeal the suspension. Already on the 60-day DL, his suspension will nevertheless be applied over this season's 41 remaining games. Passan says that the 39-year-old former MVP is expected to retire rather than sit out the 64 additional games at the beginning of next year.
After failing to make a big-league appearance in 2012, Tejada signed a minor league deal with the Royals this past off-season. Appearing primarily at second and third, Tejada had posted a reasonably productive .288/.317/.378 line over 167 plate appearances for the Royals this season.
