Zack Moss out for the playoffs with ankle injury

The Bills placed Moss on Injured Reserve on Tuesday

Zack Moss' 2020 rookie season is over after the Buffalo Bills announced on Tuesday that the running back has been placed on Injured Reserve.

NFL Network insider Ian Rapoport first reported that Moss would miss the remainder of the 2020 NFL Playoffs on Monday after he suffered his ankle injury in Saturday's AFC Wild Card Round win over the Indianapolis Colts at Bills Stadium in Orchard Park.

Shortly following Saturday's win, it was NFL Network reporter Mike Garafolo who said the fear from the organization was that his postseason would be over due to the injury suffered early in the fourth quarter.

When originally asked about the severity of Moss' injury in his weekly Zoom conference call on Monday, Bills head coach Sean McDermott never gave any clarity on how long the 23-year-old will be out of the lineup. However, he did say with Moss out of the lineup, he has the belief in the other running backs in the group to step up in his place.

"With Zack being out, we'll look at guys on our roster that we have a lot of confidence in with T.J. [Yeldon], Antonio [Williams] and Christian [Wade] there. We'll take a look at what our options are, and like I said, we have a lot of confidence in all three of those guys."

In his first season in the NFL out of Utah, Moss carried the ball 112 times for 481 yards, while also finding the end zone four times on the ground. In the air, Moss contributed with 14 receptions for 95 yards and a touchdown.

The biggest question going forward for the Bills now is, who will fill in behind second-year running back Devin Singletary as the No. 2 option in the backfield?

T.J. Yeldon has only played three games for the Bills this season, contributing 10 rushes for 70 yards, while also catching a 22-yard touchdown pass from quarterback Josh Allen in Buffalo's Week 5 loss to the Tennessee Titans.

Antonio Williams has been on-and-off the Bills' practice squad this season after being signed as an undrafted free agent out of North Carolina this offseason. However, he did garner the attention of Bills fans in the regular season finale against the Miami Dolphins, where he rushed for 63 yards on 12 carries and found the end zone twice.

Buffalo also has Taiwan Jones available on the roster if they needed an extra option in the backfield, however, he has been utilized more as a special team contributor this season.

While McDermott did mention Christian Wade when talking about options in the running backs room to replace Moss in the lineup, the former English rugby player is still ineligible to be promoted to the active roster this season due to him being designated as part of the NFL's International Player Pathway program.

Buffalo also looked to the free agent market to make an addition, as the team announced on Tuesday the signing of veteran running back Devonta Freeman to the practice squad.

The Bills are gearing up for their AFC Divisional Round matchup with the Baltimore Ravens this Saturday night at Bills Stadium. Kickoff on Saturday is set for 8:15 p.m. EST and can be heard on WGR with John Murphy, Steve Tasker and Sal Capaccio on the call.
