Broncos' Wade Phillips hospitalized but alert after taking sideline hit

— -- DENVER -- Denver Broncos defensive coordinator Wade Phillips was taken from the sideline on a backboard Sunday after he was knocked to the ground during Broncos cornerback  Bradley Roby's interception return for a touchdown.

A team spokesman said Phillips was taken to a local hospital in an ambulance, adding that he was alert and moving all extremities and would undergo further tests.

The team later announced all of Phillip's precautionary test results were normal so far.

Roby intercepted a tipped pass with just over nine minutes remaining in the second quarter of Sunday's game against the Chargers. As he ran up the Broncos sideline during the return, Chargers running back Melvin Gordon was blocked into Phillips, who was standing several feet back from the sideline.

Phillips, 69, fell to the ground, and video showed that the back of his head struck the ground. Players quickly waved Denver's training staff over to help Phillips.

Phillips was secured to a backboard, with his head immobilized, and taken off the field on a cart. Broncos coach Gary Kubiak talked to Phillips as he as was about to be taken from the field, and Phillips appeared to answer Kubiak.

Phillips also waved the No. 1 sign with his right index finger as the cart was driven away.
