Kris Bryant exited Tuesday's Cubs-Cardinals game in the fifth inning.
The Cubs said an inning later Bryant exited with hamstring fatigue.
In between, fans all over the baseball map speculated of a potential trade of Bryant, one of the Cubs' top trade chips.
Bryant appeared in discomfort after making a diving catch in left in the third inning. He ranged to his left in the left-center field gap, laying out to make the grab.
Manager David Ross postgame described Bryant, who had a short All-Star break while playing in the Midsummer Classic, as having "heavy legs."
"There was no sense pushing somebody that didn't have a didn't have much of an All-Star break," Ross said.
Ross added Bryant was feeling better after getting treatment with the training staff and didn't rule out him playing Wednesday.
Bryant also left the game on July 7 against the Phillies with hamstring tightness.
Ian Happ replaced Bryant in left field, later coming up with the game-winning hit during a six-run, ninth-inning rally.
