Rockies' Gerardo Parra (ankle) thinks he can return in 2-3 weeks

Colorado Rockies left fielder Gerardo Parra is headed to the 15-day disabled list after suffering a high left ankle sprain, but he told ESPN's Marly Rivera that he thinks he will be able to return in two to three weeks.

Rockies manager Walt Weiss said Wednesday that an MRI revealed the extent of the injury and that Parra will be placed on the DL before Friday's game in Miami.

"I was really scared yesterday. I really thought it was much more serious, but thank God it was no big deal," Parra told Rivera. "I have some stretched ligaments in the upper part of the ankle.

"There is no tear, no fracture, no tendon damage."

Parra received a cortisone injection and was wearing a walking boot in the Rockies' clubhouse.

Parra was hurt during Tuesday's 13-10 win over the New York Yankees while attempting to field a fly out by Jacoby Ellsbury, who was leading off the top of the third. As Parra settled under the shallow fly, rookie shortstop Trevor Story made a diving attempt at the ball and rolled over Parra's lower left leg.

Parra slammed the outfield grass with his right hand, and the team trainers came out to him. He was helped onto a cart and taken off the field.

Parra said Wednesday that he spoke with Story to reassure him that "he should not worry about what happened."

"I called for the ball, and unfortunately, he didn't hear me," Parra told Rivera. "Just as he plays hard, I play hard, and it's just a part of baseball. We all want to make every play. We all want to make every out. It has nothing to do with being a rookie or being veteran; it can happen to anyone."

Parra is hitting .263 with five home runs and 27 RBIs in his first season with Colorado.
