"Wide receiver Anthony Gonzalez hasn't had an ankle injury since he was a high school freshman, so he's flying somewhat blind with the high, right ankle sprain suffered when he was tackled during the Sept. 12 season opener at Houston.

"They're saying four to six (weeks)," Gonzalez said. "I obviously hope to be on the short end of that. Everything I'm doing is designed to get back as soon as possible.

"The doctors and trainers tell me I'm ahead of schedule."

If he's out four weeks, he could return for the Oct. 17 game at Washington. The Colts' bye week is Oct. 24.

It has been a tough couple of seasons for Gonzalez. He missed all but part of the first game last season with a right knee injury."
