BOURBONNIAS, Ill. -- A pair of Chicago Bears' defenders were unable to finish Friday's practice, as starting cornerback Kyle Fuller suffered a minor ankle injury, and rookie defensive tackle Eddie Goldman left the field early because of dehydration.

Neither situation is believed to be serious.

"[Fuller] tweaked his ankle," Bears coach John Fox said. "We did back off him some at the later stages of practice."

Fox announced he excused veteran tight end Dante Rosario from practice for personal reasons.

Friday's non-padded session featured the first scuffle of training camp. It began during a team drill when right guard Kyle Long took exception to defensive end Jarvis Jenkins' treatment of running back Jacquizz Rodgers after the whistle. Unhappy with Jenkins, Long shoved the defensive end, who in turn pushed Long, causing the two-time Pro Bowl offensive lineman to temporarily lose his balance. Teammates then stepped in to break up the altercation.

Minor fights such as these are commonplace at NFL training camps across the league.

"That [scuffle] is a good thing," Bears outside linebacker Pernell McPhee said. "That's just like we're all family. You know, brothers fight. It's just being competitive, being one of the guys out there. I don't know what it was before but I tell them all the time, 'we're dogs. I've got your back, go out there and fight and win, every brother.'"

Fox added: "I mean this is a combative game played by combative people. You try to discourage it, but I'm sure this won't be the last one, I can pretty much guarantee that."
