D'Andre Swift, who had been slowed by a groin injury throughout the preseason, is expected to be ready to go with no limitations for the Detroit Lions in Sunday's season opener against the San Francisco 49ers.

Lions coaches had expressed concerns during training camp about Swift's status.

"I'm very bad at counting reps," Lions running backs coach Duce Staley said. "If he's out there being productive ... I don't know how to take him off.

"I get caught up in the game, he's gonna get caught up in the game and every good player -- every good running back that I know anyway -- once he starts feeling it, you don't want to pull him off. We can count the reps Monday."
