"It's hanging on … hopefully it will leave him," Black said.
Maybin started the game in center field and went 1-for-2 with a double before leaving in the seventh inning as he was playing defense.
Black said Maybin was sick to his stomach in the hallway area that leads from the home dugout to the clubhouse and again out in center field.
Maybin has performed well offensively in a small sample-size since returning from the disabled list on April 27. His double Monday was his ninth hit in 25 at-bats since coming back from the ruptured left biceps tendon injury he incurred March 2 while making a diving catch in a Spring Training game.
Will Venable, who had a two-run single in the bottom of the 12th inning in Monday's 6-5 victory, got the start in center field Tuesday.
