Source: Lions RB Jahmyr Gibbs suffered a hamstring injury at today’s practice.

Related players: David Montgomery, Craig Reynolds, Sione Vaki, Zonovan Knight

This will be worth monitoring until we find out just how serious this is. Hamstring injuries, of course, can be very tricky. If Gibbs has to miss any time or games to start the season, Montgomery would likely get a bulk of the work with Reynolds next up. The loss of the dynamic Gibbs would certainly change the Lions offensive attack. The rookie Vaki could get to see more time if Gibbs is out for a while.
