Jose Lobaton came up with a sore right shoulder after attempting to throw out Tigers catcher Alex Avila during Thursday's 7-2 loss.
On Friday morning, Lobaton wasn't sure of the condition of his shoulder. He has not been put on the disabled list, but the Rays' backup catcher didn't sound that optimistic while categorizing his situation as day to day.
"I didn't throw a ball, but I don't think I'm going to be available to catch, but I'll be ready to hit," Lobaton. "Let's see how it is tomorrow, if tomorrow's fine to throw. I'm not sure what the trainers are trying to do yet."
When asked if he could play through the problem if he needed to, Lobaton said, "I don't know."
"I want to play 100 percent," Lobaton said. "Being a catcher, throwing guys out at second, it's hard. If it feels 80 percent, I can play, but at 50 percent, it's hard. For a catcher, it's tough to throw guys out. I'm going to be working hard day today and see if I can be good in a couple of days."
Lobaton said he had not seen a doctor on Thursday, but he did receive treatment in the training room.
If Lobaton's problem lingers, the catching duties would fall to starter Jose Molina and Stephen Vogt, which presents some obstacles. First, 81 games is the most Molina has started in one season, so it's not likely he can shoulder the entire load. Meanwhile, Vogt is on the team because of his offense and his catching is a work in progress.
Chris Gimenez, who is nursing a groin problem, and Nevin Ashley are possibilities who could be called up, too.
"They haven't said anything [about the disabled list]," Lobaton said. "To me, I don't want to [go on the DL], but whatever they want. I know we've got Vogt here, [so] that's good right now, we have another catcher."
Other than being able to get behind the plate, Lobaton said he was ready for duty.
"If they need me to hit today or pinch run, steal a base, huh?" Lobaton said.
