Campbell was a limited participant in practice Wednesday.
According to Ian Rapoport of NFL Network, Campbell's groin injury is viewed as more of a lingering issue than a new concern. If the injury doesn't prevent Campbell from playing Sunday against the Seahawks, he'll begin the season as the Colts' No. 3 receiver with T.Y. Hilton out multiple weeks after neck surgery. He'll likely work in the slot role, with Zach Pascal playing outside in three-wideout sets.
