Redskins coach Mike Shanahan got so close to the action at Monday's practice that he became part of it and was planted by rookie defensive back Brandyn Thompson.
Shanahan remained on the ground for several minutes and the Redskins said he was fine but "woozy" after the incident and would unavailable to meet with media as planned.
"It was pretty bad looking," linebacker London Fletcher said. "Definitely a very scary feeling for awhile."
Rookie quarterback Robert Griffin III showed his loose personality when asked about Shanahan being knocked over in the wide receiver-cornerback drill.
"He showed some toughness," Griffin said. "That's a benchmark of our team."
