Ryan worked with the first-team offense, but No. 2 quarterback Chris Redman took snaps with the starters, too.
A two-time Pro Bowl selection, Ryan has been sacked nine times, third most in the NFL. Philadelphia and Chicago combined to hit him 17 times.
The Falcons (1-1) have won five straight over Tampa Bay (1-1), but Ryan has thrown eight interceptions and been sacked seven times in six starts against the Bucs.
In 2009 at the Georgia Dome, Ryan left with a turf toe injury after the Buccaneers sacked him in the first quarter. He missed losses over the next two weeks.
