The Saints have another quarterback on their roster.

The team claimed Joe Callahan, who was waived by the Packers, and cut offensive tackle Khalif Barnes to make room for the new addition.

The rookie completed 61.4 of his passes during the preseason with three touchdowns, and no interceptions for an 88.2 quarterback rating over 182 snaps.

The Packers were impressed enough with the rookie to carry him on the active roster coming out of camp. And the Saints, who had one of the higher waiver claims in the league, were obviously intrigued by what Callahan put on film.

Signed as an undrafted free agent out of Wesley, the 6-foot-1 quarterback completed 915 of 1,420 passes for 12,852 yards and 130 touchdowns with 38 interceptions. He led the Division III school to a 33-7 record during that span.

New Orleans is currently carrying Drew Brees and Luke McCown on the 53-man roster. It waived Garrett Grayson, a 2015 third-round pick, last month and signed him to the practice squad.

Barnes has bounced off and on the roster since the end of training camp.
