The New York Giants are signing veteran quarterback Mike Glennon to serve as the backup to Daniel Jones, a source confirmed.
Glennon replaces Colt McCoy, who is currently a free agent. The Giants had spoken to McCoy about a potential return after he filled in admirably during a pair of starts, including a stunning upset of the Seattle Seahawks.
Glennon, 31, spent last season in Jacksonville. He started five games and threw for 1,072 yards with seven touchdown passes and five interceptions.
The Giants will be his sixth team in six years.
