BEREA, Ohio -- Myles Garrett admitted that his high ankle sprain affected him "a good bit" in the second half of Sunday's loss to the Jets.

Garrett played situationally, and had two sacks in the first half, one on his NFL snap when he lined up and rushed inside. The second half, though, he was laboring noticeably.

"It was sore," Garrett said Wednesday. "Something I hadn't been used to. First game. Was already in a ... not uncomfortable environment ... but a new environment. It was something I hadn't done regular season. But it should be better this game."

Garrett was effective early in the game, with two sacks in the first half. His two sacks on 19 snaps made him the first No. 1 overall pick to register two sacks in his debut. But in the fourth quarter when he was most needed, he was spent. The only time he saw the field was when Carl Nassib was shaken up, and it was obvious Garrett was having trouble pushing off the leg.

What seems evident is that Garrett is not full-strength, and may not be for some time as he tries to play while the ankle heals.

"It just takes time," Garrett said. "Making sure that I'm doing everything that I can and I'm managing my time wisely. Whenever I have some free time in there, getting more treatment and make sure that I can keep this behind me."

The Browns are in the situation where they want the first overall pick on the field, but they don't want to risk his long-term health. Thus they limited him to third downs and situations against the Jets. Problem was he ran out of giddy-up.

During the game, Garrett had to ride the bike and keep moving on the sideline to keep the ankle warm, but by the second half even that wasn't helping.

He said the ankle felt better Wednesday than Sunday, but it appears this will be a situation to monitor all season.

"It just depends on how it responds this week and how I respond this week," Garrett said of Sunday's game in Houston. "If I have a good week of practice and it feels good then I can get some more snaps and play a little bit more in the fourth quarter and bring more to the table."
