The break is not confirmed because Carroll hasn't had it X-rayed, because he doesn't want to know if the tip of the index finger on his throwing hand actually is broken.
"It doesn't matter if it is or not," said Carroll. "It looks broken, but you just deal with it. I don't think it affects me. It just looks funny."
Carroll said he suffered the injury taking ground balls on Aug. 3, the day Furcal was disabled with a lower back strain. He said he doesn't tape the injury, having broken the tip of the middle finger in the past and found the tape didn't help.
"It's no big deal," he said, downplaying the pain. "At this time of the year, everybody is banged up and hurt some place or other."
Carroll has committed only four errors in 489 innings at shortstop this year, having started 55 games. In August, he's hit .315 and leads the club with a .412 on-base percentage. Overall he's hitting .284 in 112 games.
