Multiple brawls overshadow Saints-Cowboys joint practice session

• Saints' Bell alert as he was driven from the field

• At least six fights mar joint practice at training camp

• Donovan Ezeiruaku ejected for throwing punches

New Orleans wide receiver Ronnie Bell was carted off the field because of the effects of Southern California heat after being involved in one of several fights during a chippy joint practice between the Saints and Dallas Cowboys on Tuesday.

He just had to go inside for a little bit. He just got a little bit overheated," New Orleans coach Kellen Moore said.
