Hayes, 24, made 45 starts over the past three years in Tampa. He was benched in November of last season for tackling poorly.
Hayes is undersized but athletic, and he could be a role player in pass coverage while also playing on special teams.
It’s worth noting that incumbent Broncos weak-side linebacker D.J. Williams is in danger of missing the first six games of the 2012 season due to suspension. Williams is challenging the ban.
