OWINGS MILLS, Md. -- The Baltimore Ravens signed Joe Callahan to provide quarterback depth until Robert Griffin III recovers from thumb injury on his throwing hand.
Callahan, 26, is on his sixth team in three years, playing one game for the Green Bay Packers in 2017. He reunites with Ravens offensive coordinator Greg Roman, who coached Callahan at Holy Spirit High School in Absecon, New Jersey.
The Ravens have been down to two quarterbacks in Lamar Jackson and Trace McSorley after Griffin injured his right hand after hitting the helmet of outside linebacker Tim Williams' helmet during Saturday's practice.
