Both players are considered day to day and will be reevaluated before Wednesday's finale.
"I think we should be OK," Porter said. "Both of those guys, it's a bruise and it's one of those things where you don't want to try to push the envelope, especially at the point we were at with J.D. It was the middle of the inning and you're out there holding up the game. It was more a question, 'Can you go right now?' Not, 'Can you go in the next 15 minutes?' We made a decision to get him out of the game, as well."
Barnes, who made yet another terrific diving catch in center field earlier in the game, said his calf was stiff and wasn't so sure it would have enough time to heal in order for him to play Wednesday.
