According to Schefter, Montgomery is undergoing additional tests on his knee and getting a second opinion, while adding that the veteran running back “could be lost for the season.” He also added that there are some in the Lions’ organization who believe Monty will be out for the season. It’s a brutal blow to the Lions, and Montgomery’s fantasy managers, as Monty has played a key role in the team’s offensive success both on the ground and through the air. Serving as the “Knuckles” to Jahmyr Gibbs’ “Sonic,” Montgomery has rushed 185 times for 775 yards and 12 rushing touchdowns this season. His 12 rushing touchdowns are tied for second-most amongst all running backs, while his 1,116 yards from scrimmage ranks 18th amongst all backs. Montgomery’s absence should set up Gibbs for high-volume weeks in the fantasy playoffs, while backup Craig Reynolds could also see an increase in playing time. Reynolds’ unpredictable workload will keep him off the fantasy radar in Week 16, although he does make for an interesting stash in deeper leagues for those still in the hunt for a championship.
