Browns' Myles Garrett has high ankle sprain

— -- Cleveland Browns?defensive end Myles Garrett?has been diagnosed with a high ankle sprain and his status will be updated in a couple of weeks, the team announced Thursday.

While Garrett has not been officially ruled out for the opener Sunday against the Pittsburgh Steelers, a typical recovery time for a high ankle sprain is 4-6 weeks.

The top overall pick in this year's draft was injured Wednesday during Cleveland's first full practice leading to the opener. It's not known how Garrett was hurt.

Garrett's loss is another blow for the Browns, who went 1-15 last season and have had their share of costly injuries in recent years.

The 6-foot-4, 275-pound Garrett was limited by a left ankle sprain last year at Texas A&M. He sprained a foot with the Browns this spring, but Browns coach Hue Jackson said he did not believe the ankle injury was related.?
