Jhonny Peralta could miss 2-3 months because of a left thumb injury, St. Louis Cardinals general manager John Mozeliak revealed on Monday.

Peralta suffered the injury on Saturday and underwent an MRI. Early tests indicate that the shortstop has a torn ligament.

"We have some history with this with Yadi (Yadier Molina)," Mozeliak said. "We've got to determine what this next step looks like."
