Oakland Athletics outfielder Boog Powell (knee) has been shut down for the remainder of the season.
Powell bruised his kneecap last week, and while an MRI revealed no structural damage, the Athletics don't want to press the issue with their young outfielder.
Powell slashed .312/.380/.494 with 3 home runs in 92 plate appearances for the Athletics after being acquired from the Seattle Mariners on August 6.
