Head coach Dan Campbell appeared optimistic Saturday that Sewell (ankle) will be good to go for Week 1 against the Rams, Colton Pouncy of The Athletic reports.
Sewell was forced to leave Wednesday's practice due to an ankle injury, but the MRI came back negative. Sewell has made the Pro Bowl in each of the last two seasons as the Lions' starting right tackle, and he has started in all 50 regular-season games he's played over the last three years.
