New York Yankees righthander Ivan Nova has a partial tear of the ulnar collateral ligament in his pitching elbow, an injury that often requires Tommy John surgery.
Nova left Saturday night's game against Tampa Bay in the fifth inning. An MRI exam after the game revealed the injury and he was placed on the 15-day disabled list.
"It's hard," Nova said. "I really don't know what to say. I'm sad right now."
Nova will be further examined Monday in New York by Yankees team physician Chris Ahmad. He had no discomfort in the elbow until his 82d and final pitch Saturday when he felt a pop.
If Nova needs elbow-ligament replacement surgery, he could be sidelined more than a year.
The Yankees also, as expected, reinstated first baseman Mark Teixeira from the 15-day disabled list and he was in the starting lineup for Sunday's game against Tampa Bay.
Teixeira hurt an adductor muscle that runs alongside the hamstring trying to make a play on a foul grounder during an April 4 game against Toronto.
Milwaukee Brewers centerfielder Carlos Gomez and Pittsburgh Pirates outfielder Travis Snider were ejected from a game Sunday after a third-inning brawl. Brewers bench coach Jerry Narron also was ejected.
Both benches cleared when Gomez and Pirates starting pitcher Gerrit Cole got in a shouting match after Gomez tripled off the wall with two outs in the third inning. Cole, upset with Gomez for flipping his bat after hitting the ball, stormed toward third base after Gomez slid in safely.
Gomez took a couple of steps toward Cole before players from both dugouts and the bullpens entered the field.
The Detroit Tigers have released opening-day shortstop Alex Gonzalez and purchased the contract of infielder Danny Worth from triple-A Toledo.
Los Angeles Dodgers lefthander Clayton Kershaw threw a simulated game on Sunday and reported no discomfort after topping out at 90 m.p.h.
Kershaw, recovering from a strained muscle in his upper back, said he felt "pretty normal" and that he expects his next step will be a rehab assignment in the minor leagues if he feels OK on Monday.
