Cubs shortstop Addison Russell left Sunday's game against the Brewers after getting hit in the face by a pitch from right-hander Adrian Houser in the top of the third inning.
Russell initially stayed in the game but came out after he scored.
"By the time he got to first base he felt like he was good," manager Joe Maddon said. "I saw the same thing. ... When he came back in they wanted to take a better look at him, so we got him out of the game at that point."
After the game, the Cubs said Russell sustained a nasal bruise and was being evaluated for concussion symptoms. He will travel to San Diego, where the Cubs play their next series, but it's unclear if he'll play Monday.
