Galeai suffered a shoulder injury during Friday night's preseason game against San Francisco, Rob Demovsky of ESPN.com reports.
Galeai may not return Friday after being evaluated for a possible shoulder injury during the first half of the exhibition game. The third-year outside linebacker is competing for a backup pass-rushing role with the Packers this preseason, and Jonathan Garvin, Kingsley Enagbare and Kobe Jones should see increased snaps during his potential absence.
