With backup quarterback Robert Griffin III sidelined after injuring his thumb during training camp practice over the weekend, the Baltimore Ravens signed Joe Callahan on Monday, according to multiple reports.
Griffin, the former NFL Offensive Rookie of the Year back in 2012 with the Washington Redskins, reportedly sustained a hairline fracture to his right thumb after it accidentally struck the helmet of linebacker Tim Williams on Saturday.
Until adding Callahan, the Ravens had only two other quarterbacks on the current roster — starter Lamar Jackson and rookie sixth-round pick Trace McSorley. Several media outlets reported earlier in the day the Ravens were turned down by journeyman Josh Johnson, who started three games as a backup for Washington last season.
Callahan, 26, has been employed by five other organizations — Green Bay, New Orleans, Cleveland, Philadelphia, Tampa Bay — since entering the league as an undrafted free agent in 2016 out of Wesley College, a Division III school in Delaware.
Callahan has played in just one game in the NFL, a Week 17 game in 2017 with the Packers against Detroit. Callahan went 5-for-7 for 11 yards in a reserve role.
