Broncos running back Melvin Gordon has been downgraded from questionable to doubtful for Week 13. Head coach Vic Fangio announced the decision when he addressed the media Friday afternoon.

Yesterday, Gordon's game day availability was a 50-50 coin toss. Today, Fangio said Gordon has a “75 percent change of not playing” with his updated injury status. He is dealing with both a hip and a shoulder injury, which forced him to miss practice this week.

If Gordon's injuries continue to affect him the way they are, rookie running back Javonte Williams will take his place. Fangio said that Williams will start no matter what if Gordon does not play on Sunday.

This would be a huge blow for the Broncos if Gordon is not activated for Sunday night's game in Kansas City against the Chiefs. He has been a key component of the team's run game, with 605 rushing yards and five touchdowns. Gordon also has 166 receiving yards and two receiving touchdowns, proving his versatility for the Broncos offense.

However, Williams is a promising replacement for the time being. He has 568 rushing yards and two rushing touchdowns in his first NFL season. The rookie also has 193 receiving yards and one receiving touchdown.

Week 13 against the 7-4 Chiefs was already set to be a challenge for the 6-5 Broncos. It's an away game, and Denver will need to put a lot of points on the board if they want to keep up with the offense of Patrick Mahomes.
