The injury hits keep coming for the Detroit Lions .
Running back David Montgomery suffered an MCL injury to his right knee Sunday in the 48-42 loss to the Buffalo Bills at Ford Field, a person with knowledge of the situation told the Free Press on Monday.
Coach Dan Campbell announced Monday afternoon that Montgomery will undergo season-ending surgery.
The initial news came an hour after news broke that defensive tackle Alim McNeill tore his ACL and cornerback Carlton Davis fractured his jaw .
Montgomery played just 30% of Detroit's offensive snaps Sunday, a total of 24, according to Pro Football Reference. Montgomery limped off the field after staying in to block in pass protection for a Lions fourth-down conversion in the second quarter. The Lions only ran the ball 15 times for a total of 48 yards in the loss after falling in an early two-touchdown hole in the second quarter.

Montgomery did return to play in the second half when he ran one time for no gain and caught four passes, but fellow running back Jahmyr Gibbs handled a bulk of the work during the attempted comeback.
Montgomery, who signed a two-year contract extension in October, had split the backfield work with Gibbs to form one of the deadliest 1-2 running back punches in the NFL. Through 14 games, Montgomery had 775 rushing yards and 12 touchdowns on 185 carries.
Gibbs, who leads the team with 1,047 rushing yards, will become the featured back with Craig Reynolds and rookie Sione Vaki as backup options.
Gibbs and Montgomery were trying to become the first running back duo to each reach 1,000 yards on a season since Jonathan Stewart and DeAngelo Williams did it for the 2009 Carolina Panthers .
