The Buccaneers placed Miller (toe) on injured reserve Wednesday, Scott Smith of the team's official site reports.
Miller's move to IR means he'll be sidelined for at least three weeks after he was diagnosed with turf toe following Sunday's loss to the Rams. After filling a depth role for the Bucs' first two games of the season, Miller occupied a regular spot in three-receiver sets Week 3 as a replacement for Antonio Brown (illness), who wasn't available after testing positive for COVID-19. Brown has not yet been activated from the reserve/COVID-19 list, but because he's believed to be previously vaccinated, he should have a decent chance at making it back for Sunday's game at New England.
