New York Mets designated hitter Jorge Polanco was placed on the 10-day injured list with a right wrist contusion, the team announced Saturday.
The veteran infielder, who hasn't played since Tuesday, had an MRI on Thursday. He has also been dealing with a leg injury.
"It's a bone bruise," manager Carlos Mendoza said. "When doctors first took a look at him, it looked like he got hit by a pitch when he didn't. In talking to him, it was just a couple of swings that he took [Tuesday] night.
"He didn't think much of it. It just got worse the following day. Just have to let it calm down a little bit and go from there. We don't have a timetable [for his return]."
The IL move is retroactive to Wednesday, and the Mets called up catcher Hayden Senger from Triple-A Syracuse in a corresponding move.
Polanco, 32, who signed a two-year, $40 million contract in the offseason, is hitting just .179 with a home run and two RBIs.
The Mets have lost 10 games in a row going after Saturday's loss to the Chicago Cubs.
The 29-year-old Senger is batting .257 with five homers and 11 RBIs in 12 games with Syracuse. His arrival gives Mendoza more flexibility with how he uses his top two catchers, Francisco Alvarez and Luis Torrens.
