"It's one of those things where you just hope for the best," McCann said. "I don't want any setbacks where it hurts a long time. ... It would hurt if I went to block a slide or a split in the dirt, so you want to get it early so that it doesn't become something significant."
Girardi does not believe that a stint on the disabled list or a Triple-A callup is necessary. Catching prospect Gary Sanchez -- ranked No. 3 in the Yankees' system by MLBPipeline.com -- is on the Minor League DL with a broken thumb suffered May 24.
"I think if we felt it might be four or five or six days, we might do something, but we could use him today if we had to," Girardi said. "So we'll wait a couple of more days, I'm sure."
Girardi said that infielder Ronald Torreyes will serve as Romine's emergency backup, if needed.
