Bolsinger, who allowed four runs on seven hits in five innings in Monday's 8-3 loss to the Brewers, was 1-2 with a 6.08 ERA in five games, including four starts, with the D-backs
The D-backs have an off-day on Thursday, followed by a three-game series at the Chicago White Sox, before returning home on Monday against the Washington Nationals.
Josh Collmenter, who started Tuesday night's game against the Brewers, could start again on Sunday. Gibson added that Chase Anderson, called up from Double-A Mobile on Tuesday to take Bolsinger's roster spot, also could be an option.
"Colie could throw that game," Gibson said. "We really wouldn't need anybody until Tuesday. Or, we could put somebody else in there. We're considering our options."
