Locker Room Buzz: Denver Broncos

DENVER -- Observed in the locker room after the Denver Broncos' 27-17 win over the Kansas City Chiefs:

Welker injured: Wide receiver Wes Welker, who has nine touchdown receptions this season, suffered a concussion on a 20-yard catch-and-run play in the fourth quarter. Welker started to leave the field and then took a knee. He had a reception later in the same drive, a 9-yard catch, but did not return to the game following that play. By the league’s concussion protocol, Welker will be limited in practice this week -- Friday would be his first full day of practice at best -- even if he passes a baseline test Monday. The Broncos play Welker’s former team, the New England Patriots, next Sunday night.

Grind it out: Running back Knowshon Moreno didn’t have the prettiest yards per carry average -- 2.9 -- but in the end he did outrush Chiefs running back Jamaal Charles 79 to 78. Moreno carried 27 times to hit that total, but that commitment to the run allowed the Broncos to keep the Kansas City pass rush away from quarterback Peyton Manning.

Zero sum: In the end, it may be the number that meant the most as Manning walked into the locker room after the game with a clean jersey. The Chiefs came into the game as the NFL’s sack leader and did not sack Manning. “We knew this would be a game where (the offensive line) would have to play well for us to have a chance,’’ Broncos interim coach Jack Del Rio said.

Julius Thomas a question mark: Thomas grabbed his right knee after a collision with a Chiefs player following an incomplete pass in the third quarter. The Broncos officially classified his injury as “lower leg,’’ but Thomas was getting treatment following the game. Joel Dreessen played as the lone tight end in the team’ three wide receiver look after Thomas left the game. Earlier in the game Thomas was the first opposing tight end to catch a TD pass this season against the Chiefs defense.
