He compiled 677 receiving yards on 62 catches with three touchdowns for the Vikings last season despite playing just nine games due to a severely sprained ankle.
He was also the NFL's top kickoff returner at the time of his ankle injury, averaging 35.9 yards per return.
Carroll said he was hopeful Rice wouldn't miss any games.
