St. Louis Cardinals first baseman Lance Berkman will undergo an MRI today, but a preliminary examination reportedly revealed that he had torn an anterior cruciate ligament making a routine play against the Dodgers on Saturday night in Los Angeles.

Berkman was pondering the immediate and long-range implications of that possibility Sunday. “If I’ve torn my ACL [anterior cruciate ligament] or something like that, I’d certainly get it fixed. But you don’t know how psychologically you’re going to come back from something like that,” Berkman, who is 36, told the St. Louis Post-Dispatch’s Joe Strauss.

Berkman knows from torn ACLs and rehab; he tore one in November 2005 and sources told Strauss that a preliminary examination by Dodgers doctors suggested a torn ACL. Berkman, who crumpled after taking a throw from shortstop Rafael Furcal and was helped off the field, was placed on the 15-day disabled list Sunday. Berkman, who was bothered by injuries in 2009 and 2010, was pondering a lengthy layoff Sunday.

“You think about it when you have a potentially major surgery at this stage of your career,” he said. “... I don’t think it’s one of those deals where you sit out a week and see where you are. I think it’s much more serious than that.”
