CHICAGO — Jazz Chisholm Jr. landed on the injured list Wednesday with the left elbow injury he incurred sliding into home plate during the Yankees' loss to the White Sox on Monday night.

How long the third baseman will be out is, at the moment, a mystery. He has been a sparkplug at the plate and in the field since his acquisition before the July 30 trade deadline.

Chisholm was placed on the 10-day IL with what the Yankees called a “left elbow sprain,” which is likely to keep him out at least 2-3 weeks but perhaps much longer.

“We’re waiting for people to still weigh in on it today,” Aaron Boone said before Wednesday night’s series finale against the White Sox, meaning a parade of additional doctors to give their opinions on the MRI results, which came back to the club immediately after Chisholm underwent testing on Tuesday. “I can tell you Jazz is pretty encouraged with how he’s feeling and stuff, so hopefully that’s a good sign of things to come.”

Boone, however, said Chisholm, who will remain with the club through the end of this six-game trip that continues with games Friday and Saturday in Detroit followed by Sunday night’s game against the Tigers in Williamsport, Pa., is “shut down” for the foreseeable future.

“He’s going through his stuff in the training room but, again, still waiting to get everyone to weigh in on it as well,” Boone said.

He added later: “We’re obviously just a couple days into this but we’re also somewhat optimistic, too.”

Asked when Chisholm might be able to swing a bat again, Boone said: “I don’t know. Again, we’re waiting on the weigh-in from all the doctors looking at it. We’ll see. I know in his mind, he feels like he could [swing] right now, which is, hopefully, a good sign.”

In further explaining that “weigh-in,” the manager said: “Waiting for everyone to weigh in on the severity of the injury and the course of: does that mean rest? What’s the steps to getting him to where he’s able to do some things physically. I think right now they’re just in there treating it, testing range of motion, seeing how it feels on the manual tests and things like that. Just waiting on that. Still.”

Chisholm was not in the clubhouse during media availability on Tuesday or Wednesday but after Monday’s game the 26-year-old said he was not “too concerned” regarding the injury being a severe one.

“Slid in, my adrenaline was still going so I didn’t feel it right away,” Chisholm said. “A half inning went by… started to feel it a little bit, went to Boonie and the trainers and told them it was throbbing a little bit…We went through all the tests, and all the tests we’ve done here have been pretty positive. I still feel it a little bit, it’s still kind of sore, but I think we’re going to be good.”

The Yankees recalled infielder Oswald Peraza, a one-time top infield prospect whose organizational standing has plummeted in the last year because of injury and his inability to hit consistently, to replace Chisholm. Oswaldo Cabrera started a second straight night at third, but Boone said Peraza will be “in the mix” for time at third in Chisholm’s absence, as will DJ LeMahieu.

The 24-year-old Peraza, beaten out for the starting shortstop job in spring training 2023 by Anthony Volpe, has hit .216 with three homers and a .605 OPS in a combined 70 games in the majors (none this season) from 2022-23. He hit .244 with eight homers and a .733 OPS in 65 games this season with Triple-A Scranton-Wilkes/Barre.

The Yankees also on Wednesday recalled righthander Will Warren to start that night’s game and designated righty reliever Enyel De Los Santos for assignment. De Los Santos, like Chisholm a trade deadline acquisition, posted a 14.21 ERA in his brief five-game stint with the Yankees.

Chisholm was a far more successful acquisition, hitting .316 with seven homers, a 1.062 OPS and five stolen bases in 14 games.

“He’s been a dynamic player for us,” Boone said. “Provided power, speed, he’s done a great job on defense, he’s been great in the room (the clubhouse). But, again, hopefully it’s something that doesn’t turn out to be too long and we can get him back.”
