Dwelley made the Falcons' initial 53-man roster Tuesday, Terrin Waack of the Falcons' official site reports.
Dwelley and Charlie Woerner signed similar contracts this offseason and will start the campaign as backups to Kyle Pitts. Dwelley played sparingly on offense in San Francisco, but he's a stout blocker and will be involved in Atlanta's running game, per Josh Kendall of The Athletic.
