The Falcons made a couple of roster moves just before heading out for their first practice Saturday morning.
They announced the signing of linebacker Jamie Winborn and released linebacker Rashad Bobino. Winborn has been a part-time starter throughout his previous eight seasons in the NFL, but it's likely the Falcons are viewing him as a dependable backup and special-teams player.
Winborn is also a top special-teams player. He led the Broncos with 11 special-teams tackles in 2007.
