The Reds say it might be more than a week before Mesoraco is able to catch. He is 0-for-2, with two walks and a strikeout, as a pinch-hitter since his injury on April 11.
Tucker Barnhart started at catcher Thursday night against the Braves.
Price said the team is moving closer to deciding what to do with right-handed starter Homer Bailey, who had surgery in September to repair a torn flexor mass tendon near his right elbow.
Bailey's rehab was moving along until he went on the 15-day disabled list Monday with an elbow ligament strain.
"We're probably going to know in the next one-to-two days what our plans are with Homer," Price said. "You spend a lot of time when you make a diagnosis, fact-finding and making sure everything you see is as it appears. That's been the time consumer, making sure it is what we think it is and finding the best way to treat it."
