An MRI of Carlos Gonzalez's left hamstring showed inflammation behind his left knee, which could sideline the all-star for the remainder of the season.

"I don't know if I will be able to play again. It's a tough spot. I want to," Gonzalez said. "I don't want to end like last year where I miss a bunch of games at the end. But it has to get better."

Gonzalez is batting .303 with 22 home runs and 85 RBIs. The Rockies have nine games remaining.
