David Montgomery (knee) is the only player missing from the active roster. The starting running back remains in limbo, with the Lions waiting to see how his recovery goes before deciding a course of action. Montgomery missed last week’s game, with Jahmyr Gibbs handling a bell-cow workload in the win.

After missing practice Thursday with an illness, rookie cornerback Terrion Arnold returned to practice Friday. Arnold was listed as a limited participant, but certainly an upgrade from Thursday and trending towards playing Monday against the 49ers.

When it comes to injuries, the Detroit Lions haven't gotten a lot of good news this season. However, on their Friday practice report, there were multiple pieces of good news for Detroit. Here's what we have for you.

The 49ers host the Lions in a Week 17 Monday Night Football game. San Francisco is out of playoff contention, while Detroit seeks the top seed. The Lions miss star running back David Montgomery, out for the season due to a torn MCL.
