The Los Angeles Angels put outfielder Mike Trout on the injured list Friday because of a bone bruise in his left knee.
The move is retroactive to Thursday.
Angels manager Ron Washington told reporters in Anaheim on Thursday night that the injury was not believed to be serious and tests didn't show any structural damage in Trout's knee, adding that he needs some time to "rest."
The star outfielder exited the Angels' game Wednesday against the Seattle Mariners because of the injury. During an at-bat in the third inning, he tried to run out a ground ball to second base. He sprinted down the line and lunged toward first and was barely out. Trout stayed in the game on defense but was pulled the next inning and replaced by pinch hitter Jo Adell.
He underwent several tests after the game and said he was hopeful it was merely scar tissue breaking up. He said he planned to play Thursday but was out of the lineup for the series opener against the Tigers.
It was the first game Trout sat out all season.
He appeared in 29 games last season before tearing the meniscus in his surgically repaired left knee and sitting out the rest of the season.
He's hitting .173 this season, with nine home runs and 18 RBIs.
In the corresponding roster moves Friday, the Angels recalled infielder Niko Kavadas from Triple-A Salt Lake.
