The injury bug bit the health-challenged Colorado Rockies in a big way Monday.
In addition to placing two players on the disabled list, the Rockies announced that left fielder Carlos Gonzalez will undergo exploratory surgery Tuesday on his swollen left index finger.
The procedure will be performed at the Cleveland Clinic, where Gonzalez was examined May 29 before going on the disabled list Wednesday. The Rockies did not announce a timetable for Gonzalez's return.
The Rockies also placed right fielder Michael Cuddyer (left shoulder strain) and right-hander Eddie Butler (right rotator cuff inflammation) on the 15-day DL.
Cuddyer landed on the DL retroactive to Friday. The 2013 National League batting champ is hitting .317 with a .500 slugging percentage, five homers and 16 RBIs in 31 games this season. He missed a month of action due to a left hamstring strain.
Butler made his major league debut Friday, allowing six runs on 10 hits in 5 1/3 innings during a start against the Los Angeles Dodgers. His DL move is retroactive to Saturday.
Both Cuddyer and Butler were due to undergo MRI exams.
Colorado selected the contract of right-hander Christian Bergman from Double-A Tulsa, and he started against the Atlanta Braves on Monday night in his major league debut.
The Rockies also recalled right-hander Chad Bettis from Triple-A Colorado Springs, where he was 2-1 with two saves and a 1.66 ERA in 11 appearances. Bettis went 0-1 with a 7.15 ERA in 11 appearances with the Rockies before being optioned to the minors on April 25.
To open a spot on the 40-man roster for Bergman, the Rockies designated Colorado Springs right-hander Wilton Lopez for assignment. Lopez opened the season with the Rockies and posted an 11.37 ERA in four relief appearances.
