DENVER (AP) — Colorado Rockies star outfielder Carlos Gonzalez had a small tumor removed from his left index finger Tuesday during a procedure at the Cleveland Clinic.
Gonzalez underwent exploratory surgery with Dr. Thomas Graham and a growth was found beneath the sheath around the muscle.
Rockies head athletic trainer Keith Dugger said these type of tumors are common and the expectation is a biopsy will determine the tumor is benign.
"These little benign tumors, which we hope it is, is probably the second most common finding in the finger besides cysts," Dugger said. "Usually repetitive trauma causes it.
"They call them cell tumors. Pretty common within the sheath of these fingers. Usually benign. Occasionally you can come up with something."
Gonzalez had his left arm in a sling after the surgery. He is expected to return to Denver Wednesday.
"It helps explain some of the things that CarGo's been dealing with and why that finger kept blowing up on him," Rockies manager Walt Weiss said. "It helps answer some of the questions we had about him.
Gonzalez has been experiencing soreness and swelling in the finger for a while. He was examined by Graham on May 29 in Cleveland. He continued to play but was placed on the 15-day DL on June 4 and is expected to miss a few weeks.
