"They got it back in and there is no other damage," interim manager Daren Brown said after the Mariners' 3-1 victory over the Rangers. "He'll be sore and I don't see him being able to throw for the next five days, but he might be able to swing the bat in a couple of days."
Lopez was in position to field a hot shot hit by Rangers designated hitter Nelson Cruz. The ball took a wicked hop and bounced higher than Lopez expected. The ball hit Lopez's bare hand and chest.
Cruz ended up with an infield single and Lopez immediately walked off the field and went into the visiting clubhouse for treatment.
Lopez, who is finishing up a subpar season while batting .240 with 10 home runs and 58 RBIs, doubled, walked and struck out in three at-bats on Tuesday.
"He has been swinging the bat well the last couple of weeks, and has had some leadoff walks to help us score some runs," Brown said.
Matt Tuiasosopo and Matt Mangini figure to share the position during the final days of the regular season.
