Padres manager Pat Murphy said prior to Tuesday night's rematch that Norris' hand was sore, but he could be used as a right-handed pinch-hitter. Austin Hedges was scheduled to start anyway and catch starter Tyson Ross.
"It'll be a game time decision," Murphy said. "He's kind of day-to-day right now. Sore."
Norris had X-rays on Monday night that we're negative, but he consulted with a Padres hand specialist on Tuesday.
"Everything is good so far," Norris said. "There were no other tests, not right now."
As for Shields: "He's fine," Murphy said. "He won't miss his next start. It's just a bruise. No window fracture."
Murphy explained that a "window fracture" is an injury that's akin to a rock hitting a windshield, sending little fractures out from the point of impact.
"I did it when I was in school. I think everybody has a window fracture when they get hit in that spot so I constantly say that," he said. "When I went to the mound last night I said, 'Looks like a window fracture to me.' Nobody appreciated it, because they don't know the back story, but I appreciated it. It's personal humor."
Shields is slated to pitch Sunday against the Rockies in Denver.
Otherwise, Murphy said he was shuffling his rotation to slip the just recalled Robbie Erlin into the rotation. He's slated to start on Saturday against the Rockies and should have at least two more starts after that. Odrisamer Despaigne goes back to the bullpen.
Casey Kelly will also get into the starting mix a little further down the road. The Padres have off days on Thursday and Monday and then play 12 games in the final 13 days. Murphy said they will go to a six-man rotation at that juncture.
"You'll see Casey Kelly inserted at some point," Murphy said. "We're finalizing that schedule right now, but Casey Kelly will get a couple of starts, too."
