One of the most anticipated debuts in Cleveland Browns history will be delayed.

One day after Browns head coach Hue Jackson revealed that rookie defensive end Myles Garrett failed to finish practice on Wednesday, the team announced Garrett has been diagnosed with a high ankle sprain. His status will be updated in a couple weeks.

“We will see," Jackson said Wednesday, prior to the diagnosis. "I don’t want to make medical decisions. I am not very good at them so we will see where we are as we move through the week.”

Garrett underwent an MRI Wednesday afternoon, according to's Mary Kay Cabot.

The No. 1 overall pick in the 2017 NFL Draft, Garrett is coming off an impressive preseason in which he was voted the winner of the Maurice Bassett Award, which is presented to the team's top rookie each training camp. In three preseason games, the Texas A&M product tallied 2 tackles and 1 sack.

Earlier on Wednesday, Garrett expressed his excitement for his upcoming NFL debut, in which he would attempt to make good on his previous promise of getting to Steelers quarterback Ben Roethlisberger.

"You shouldn’t be scared to take anybody down," Garrett said. "We are going to come at him as a collective group. It is not just one player getting after five guys. It is our whole defense against their offense. I’m not going to be alone in this.”
