WR Dobson sits after scrap

PHILADEPHIA -- The Patriots and Eagles practiced for nearly three hours on Tuesday, and there was a lot to digest on the field. By all accounts, it was a productive practice for both teams.

There were also some fireworks.

About midway through the practice, Patriots rookie receiver Aaron Dobson was blocking on a running play during 11-on-11 drills and was engaged with five-year veteran Cary Williams when Williams appeared to take exception and raised his hands toward Dobson's helmet.

There was some brief pushing, officials on hand were blowing their whistles constantly, and players from both teams formed a minor scrum around Dobson and Williams before the situation was quickly extinguished.

Dobson and Williams didn't participate in the rest of practice.

After the practice, Eagles coach Chip Kelly explained that he spoke with Bill Belichick beforehand and they both agreed that players involved in scraps would be held out for the remainder of practice.

"We didn't want this to turn into a wrestling match," Kelly said.
