DENVER -- Jonathan Herrera became concerned about an infection on his left wrist early Tuesday morning and was admitted to a local hospital for treatment, the Rockies announced.
The infection came from Herrera's wrist watch, Rockies manager Jim Tracy said.
"He contracted some type of infection, I know they did a culture, but I don't know anything further than that," Tracy said. "He went to the hospital around 2 a.m. this morning; he was very, very concerned about it."
Herrera, a utility infielder, was added to the 15-day disabled list, retroactive to July 16.
"This [treatment and recovery period] will take several days, but we can't play that short-handedly for that long a period of time, so we had to place him on the disabled list," Tracy said.
To fill Herrera's spot on the the 25-man roster, the Rockies called up outfielder Andrew Brown from Colorado Springs.
Herrera, 27, spent 30 days on the disabled list with a strained right hamstring from May 23-June 22. In 45 games he has hit .246 with three home runs and six RBIs.
