X-rays showed no break in the hand, but Bergman will soon undergo an MRI after his hand showed severe swelling on Saturday morning.
If Bergman can't start, it'll be yet another blow in a year full of injuries to the starting rotation. Left-hander Christian Friedrich, who made his 2013 debut on Saturday against the Brewers, became the 11th starting pitcher the club has used this season.
"It's still pretty sore," Bergman said. "I wasn't able to grip a bat last night and I still can't hold a bat today.
"I'm not sure [if I can start Wednesday]. I'll be getting some treatment, so we'll have to see how it goes."
