Denver Broncos wide receiver Wes Welker is all set to play against the New England Patriots with interim coach Jack Del Rio saying he's "definite" for Sunday night.

Welker underwent concussion testing as part of the NFL protocol and participated fully Friday.

"First and foremost, we've done the right thing by the player and he's safe to return,'' Del Rio said. "That's first and foremost. It's kind of like Peyton a while back: If you had a 'definitely will go' category, he'll probably be on there. He'll play.''

Welker got hurt against the Kansas City Chiefs, leaving the game with a concussion and a neck injury in the fourth quarter.

Welker went back in the game and caught another pass before being taken out of the game..

Welker said Thursday he was coming along well.
