Toronto's hopes for a quick start in baseball's American League East this season might have taken a hit.

Newly acquired third baseman Scott Rolen broke a finger during a fielding drill on Sunday afternoon in Dunedin, Fla., and is out indefinitely, the Blue Jays announced.

Rolen was hit on the tip of a digit by a ball that "ripped his nail completely off his finger," general manager J.P. Ricciardi said.

Rolen also suffered a broken top knuckle on his right middle finger.

Ricciardi said the fracture was "non displaced, … which is good news."

The GM added that "the early prognosis is it isn't going to be six weeks, so I don't even want to throw a schedule out there. Our best-case scenario is that it's quick and our worst-case is it isn't as long as most things we have had to deal with."

Rolen was headed to Baltimore on Sunday for a Monday appointment with specialist Dr. Thomas Graham.

Toronto sent third basemen Troy Glaus to St. Louis this past winter for Rolen, who has struggled with injuries the last few seasons.

Marco Scutaro will fill in at third base while Rolen is gone.
