Chicago Cubs star Kris Bryant exited Monday's game against the Pittsburgh Pirates in the fifth inning due to right lower oblique tightness.
Bryant was 0-for-1 in the contest before being lifted.
The 2016 National League MVP spent two weeks on the injured list earlier this season due to a sprained finger he originally suffered during an Aug. 12 game against Cleveland.
This season has been a rough go for Bryant, even when he's been healthy enough to play. Entering Monday's action, he was on pace to set career-lows in batting average (.
