One day after Troy Tulowitzki's season officially came to an end, the Rockies' next injury domino fell Thursday night as the team announced Carlos Gonzalez will undergo surgery on his left patella tendon on Monday.

The operation will be performed by Dr. Tom Hackett in Frisco, Colo. Expected recovery time for the surgery is five to six months and Gonzalez has been told he'll be ready in time for Spring Training.

On Thursday evening, Gonzalez sat down with the Rockies training staff as well as consulting doctors and his agent to discuss all available options. Platelet-rich plasma and stem cell treatments were also on the table, but Gonzalez said doctors informed him those procedures would only make him feel better "for a short period of time."

"Of course, this wasn't something that I was looking for, but I know we're looking for results," Gonzalez said. "We're looking to get something done so I don't have to deal with this."

Earlier in the day, Gonzalez confirmed that Wednesday's MRI showed that his knee has more damage than previously thought with increased irritation to his patella tendon. Doctors have a good idea of the damage, but they won't know all the specifics until they begin the surgery.
