Rafael Furcal: I've already covered it in this very article, but Furcal's injury is worth repeating as it may be career ending.
The shortstop went down last August with an elbow injury. And even though in the early offseason Mozeliak had confidence Furcal would make a comeback Opening Day, the inflammation returned and he's out indefinitely.
Furcal had ligament replacement surgery last week, and Dr. James Andrews is confident he'll be ready to go next year. But some are still worried we may have seen the last of him.
Marc Rzepczynski: There have been some curious injuries in baseball, and now southpaw reliever Rzepczynski joins the club.
His left eye was compromised during a round of golf last week, but an eye doctor has given him clearance to throw, and he has since had a bullpen session. As long as there is inflammation, Rzepczynski will have blurred vision, but the effects shouldn't be permanent.
Losing Rzepczynski would mean losing one of the Cardinals' only two lefties in the bullpen, a speedy recovery is essential.
Chris Carpenter: It's impossible to talk about disappointing Cardinal injuries without mentioning Carpenter. The reality that he may never pitch again has begun to set in for fans, but that doesn't make it any less devastating of a blow for the club.
Carpenter was sidelined for most of 2012 with thoracic outlet syndrome before having surgery in which one of his ribs was removed. He made a dramatic and unexpected comeback late in the season, and it seemed like the Cards might have their ace in 2013. But that's not the case as his shoulder pain hasn't subsided.
The Cardinals have a ton of young arms itching for their chance in the majors. Who might step up in his stead?
