Montgomery dove into a pile trying to recover a fumble, and Joseph grabbed him by the leg as if to pull him out. Montgomery mule-kicked back at him, and Joseph kicked him back. Joseph was flagged on the play.
“I think I have to protect myself,” Montgomery said, via Rich Campbell of the Washington Times. “If the guy is dragging me across the ground and potentially twisting my ankle or whatever else, I’m not going to let the guy drag me across the ground. And I can’t push him, obviously, because I’m on the ground, so I used my leg to get him off me.”
Montgomery has a reasonable case, as someone (wearing a striped shirt) should have been there to keep Joseph’s hands (and feet) off him.
UPDATE 3:29 p.m. ET: According to USA Today‘s Mike Garafolo, Joseph was fined $7,875 for his role in the incident.
