Troy Tulowitzki is done for the season and outfielder Carlos Gonzalez is likely done, too, after playing in just 70 games.

The Rockies' outfielder underwent another examination Wednesday on his aching left knee. The MRI revealed more damage than a previous test, so Gonzalez will consult with the team's training staff and various doctors on Thursday to decide on a treatment plan.

"(The MRI) did show some changes from his previous MRI on his patella tendon, meaning that it is getting worse," trainer Keith Dugger said. "The irritation to the area is a little worse off than it was when we did one earlier in the year."

Gonzalez, 28, has suffered from left knee tendinitis since last season, and it's bothered him acutely at times this season. He was placed on the 15-day disabled list Sunday.

According to Dugger, the Rockies are exploring a number of treatment options, including surgery or treatments such as plasma-rich platelets or stem-cell therapy.

The only way CarGo will play again this season is if it's decided that rest and rehab will allow him back on the field. That is an unlikely scenario.

Thursday, Gonzalez will meet with Dr. Thomas Hackett, of Frisco, who performed the MRI. Also taking part in the consultation will be Rockies medical director Dr. Thomas J. Noonan, Rockies rehab coordinator Scott Murayama, and Dugger.
