Ok, maybe 'fight' isn't the best choice of words. How about scuffle?
Here's the gist of the altercation.
Offensive guard Kyle Long thought that defensive end Jarvis Jenkins went a little hard at running back Jacquizz Rodgers after a play. Long let Jenkins know about it, there was a brief altercation, the two players were quickly separated. The pads don't go on until tomorrow, but...
Considering they're still not in pads, we just saw a pretty physical period of team drills. Players making that a point of emphasis this yr.
