Dez Bryant strains hamstring; Kenneth Boatright taken to hospital

OXNARD, Calif. -- Dallas Cowboys wide receiver Dez Bryant was unable to finish Thursday's practice after suffering a left hamstring strain in seven-on-seven drills.

Bryant remained on the field for the remainder of practice, and as he walked off the field afterward, he said the leg was tight but that he would be OK.

He reassured fans later via Twitter:

Bryant had dunked the ball over the goalpost after making a catch near the goal line from Tony Romo, but he said the leg started to grab on the next play, a swing pass to running back Joseph Randle.

Bryant limped off from the back of the end zone and walked to head athletic trainer Jim Maurer. After a quick talk, Bryant handed Maurer his helmet and spoke with coach Jason Garrett.

At the start of training camp, the Cowboys said they wanted to ease Bryant into practice after he missed the offseason program as he awaited his five-year, $70 million contract. Bryant was held out of one-on-one drills on the first day of practice, but he had taken a regular turn since.

The Cowboys are off Friday and will return to practice Saturday.

"Someone like Dez, of course [there's worry]," executive vice president Stephen Jones said, "but we think he is going to be fine."

Of more pressing concern for the Cowboys is the health of defensive end Kenneth Boatright.

He suffered a neck injury after colliding with left tackle Tyron Smith. As a precaution, the team's medical staff removed his face mask and strapped him to a board. He was moving his legs but was taken to a local hospital for more tests.

"We're monitoring it by the minute here so we're on the phone with them there at the [hospital]," owner and general manager Jerry Jones said. "We don't want to not have any basis of reaction here. We don't know the seriousness of it at all."
