The Cubs called the injury a mild sprain.
"I don't know," Maddon said when asked if Bryant will miss time. "I honestly don't know. You saw him jog off the field. I don't want to create conjecture. Let's see what happens with the test."
Bryant was hit by pitches twice Thursday, though it was an awkward step on a base that forced Maddon to pull him from the game.
Bryant is hitting .289 with a .372 on-base percentage, four home runs and 15 RBIs this season.
