Detroit Lions running back Jahmyr Gibbs has reported feeling 98 to 100 percent healthy as he prepares for the regular-season opener against the Rams. Despite a recent hamstring injury, both Gibbs and coach Dan Campbell are optimistic about his availability for the game. Gibbs expressed increased confidence heading into his second year, highlighting his explosive potential in the backfield. However, there is a possibility that David Montgomery may see more action if Gibbs is not fully fit by the end of the practice week.
