It happened on a red zone route over the middle. He was EJ Manuel's intended target on the play, but Johnson and the ball never met. The ball went sailing through the end zone and Buffalo's top wideout was hopping on his right leg and clutching the back of his left. Head coach Doug Marrone provided details.
"Obviously everyone saw Stevie at the end with a hamstring," said Marrone. "He's going to get evaluated. It's always tough when those situations happen with the players."
Kevin Kolb watched the whole thing as he was not in on the play, but standing 10 yards behind the line of scrimmage.
"I saw it as soon as it happened. My eyes were on him, pre-snap I thought it was going there," Kolb said. "I haven't been in the training room yet to see what's going on."
On a day when the offense had its best day of camp they lost their top receiving weapon. Knowing there are two new quarterbacks looking to get acclimated to Johnson's unorthodox route running they know any time they're not working with Johnson makes the job more challenging.
"I want as much work with Stevie as I can possibly get," Kolb said. "My confidence level with him is through the roof. I know he's going to win, I do. I know he's going to win inside. So I trust him and now it's just a matter of getting my feet right there with me, with my mind and putting all those in the same pattern where we can be right on stride every time."
Marrone did not know the severity of Johnson's hamstring injury after practice, but he tried to put the injury in perspective knowing the team is still more than a week away from their first preseason game.
"I would say it would be a major concern when we talking about during the season, but right now a veteran player that's proven himself, we'll just see what the doctors say," said Marrone. "It is what it is and we'll deal with it from there."
Hip injury for CaussinTight end Mike Caussin also left Friday's practice early with a hip injury. He too is be further evaluated to determine when he'll be able to return to action.
