Wide receiver Malcolm Kelly has suffered a pulled hamstring, but the injury is not thought to be serious.
Kelly worked with athletic trainers during Saturday morning's practice.
"He has a little bit of a pull," head coach Mike Shanahan said. "He's getting treatment. I don't think it's a bad pull, so hopefully in the next couple of days he'll be ready."
Kelly initially suffered the injury last week working with Donovan McNabb in Arizona. Still, Kelly was able to participate in the first two days of training camp.
Explained Shanahan: "He went out there [on Friday] and he didn't feel like he could go full speed, so he did a couple of reps and he felt a twinge in there. The trainers and doctors felt it was in his best interests to get some treatment. When he's ready to go full speed, he'll be out there."
Shanahan added: "I told [Kelly], 'You have to be smart. You just can't go out there and set yourself back another two weeks.' I think he'll know. 'Just be smart. Don't come back a day early and set yourself back. You know your body.'"
Given the competition at wide receiver, the injury is a setback for Kelly.
A 2008 second-round draft pick, Kelly is not a certainty to make the final roster. He is competing for playing time with Joey Galloway, Roydell Williams, Devin Thomas and Anthony Armstrong, among others.
"Any time you miss reps, you're giving somebody an opportunity to win a position," Shanahan said. "Obviously it doesn't help. Nothing he can do about it except get treatment and see what he can do to get back out there."
-- HALL WITH A PICK
DeAngelo Hall capitalized on a bad throw by Donovan McNabb, picking off a pass and returning it for a touchdown.
On the play, Chris Cooley ran a sideline route, but Hall made the right read. He stepped in front of McNabb's pass for the easy interception.
Hall had a clear route to the end zone.
Credit Clinton Portis for trying to stop Hall. Portis raced over for the tackle, but London Fletcher blocked him out of the way of the fleet-footed Hall.
Portis and Fletcher playfully tumbled on the ground as the crowd roared in laughter.
Said Hall of his interception: "We were kind of going over what we thought was going to happen when they threw the ball. We haven't had a lot of chances to make plays in the first couple practices. We aren't getting a lot of balls. I don't know if they're not throwing it or we're not covering. But we still have a long way to go."
