"I'm set to play catch," McAllister said. "As long as it takes for me to get ready, it can be sooner than later, but I can't control that."
McAllister is 4-5 with a 3.43 ERA over 11 starts this season. In his last outing, he surrendered a season-high five runs to Tampa Bay.
"I could feel it a little bit after my start," he said. "Obviously, I didn't throw my curveball, so I didn't feel it at all because I didn't throw it. But I knew that if I would have thrown it, it probably wouldn't have felt too good."
