Byron Buxton's 2014 may have ended just like it began -- at a doctor's office.

MLB.com's top prospect dislocated his left middle finger Monday diving for a ball during an Arizona Fall League game, the Twins confirmed. The St. Paul Pioneer Press reported Tuesday that Buxton also suffered a small fracture in the finger, according to Twins farm director Brad Steil, effectively ending Buxton's fall campaign.

Despite the setbacks, Buxton remained upbeat on Twitter.

This has been a tough year but still blessed to play while I could. Gonna get healthy and come back at it next year. #determined #thankful - Byron Buxton (@OfficialBuck103) October 29, 2014

Buxton was taken for X-rays after injuring the finger in the Salt River-Mesa game. The outfielder later told MLB.com's William Boor the finger is, "All right. Throbbing a little bit, but stuff happens."

The Twins prospect was playing in the AFL after missing most of the 2014 season due to wrist and head injuries. The 20-year-old missed all of April after injuring his wrist in Spring Training, returning in early May and playing 30 games with Class A Advanced Fort Myers.

After being called up to Double-A New Britain, Buxton suffered a concussion in his first Eastern League game in an outfield collision. The head injury kept the center fielder out of action until the AFL season began.

Buxton hit .263 in 13 AFL games with Salt River. The outfielder was named to the East Division Fall Stars team on Monday.
