Matt Flynn is coming back to Louisiana.

With Luke McCown battling what is likely to be a season-ending back injury, the Saints reached an agreement to bring Flynn to New Orleans on Monday evening, according to a source.

“Looks like my hunting season is over,” Flynn wrote on Twitter, adding an emoticon of a fluer de lis to his message.

Coach Sean Payton confirmed the signing during his weekly appearance on WWL radio.

Flynn, 30, appeared in seven games last season for the Green Bay Packers as a backup. He appeared in five games in 2013, four as a starter, and completed 102 of 166 passes for 1,146 yards with seven touchdowns and four interceptions.

The LSU product was a seventh-round pick of the Packers in 2008. He also spent time with the Seattle Seahawks, Oakland Raiders and Buffalo Bills.

McCown suffered a back injury last week and will undergo surgery Tuesday, which will likely end his season, according to a source.

It’s not known how McCown became injured. He practiced Wednesday, but missed Thursday and Friday’s sessions and was inactive for Sunday’s loss against the Tennessee Titans. Punter Thomas Morstead served as the holder on the field-goal unit in his place.

McCown signed a one-year, $1.05 million contract to return to New Orleans this offseason.

The veteran McCown started against the Carolina Panthers during Week 3 in place of the injured Drew Brees. McCown completed 32 of 39 passes for 335 yards during the 27-22 loss.

New Orleans also drafted quarterback Garrett Grayson in the third round. He served as the backup during Sunday’s game, but this move seems to be a clear indication that the Saints believe he is still at least a year away from being able to handle the role.

Flynn returns to Louisiana, the state where he once delivered a championship.

His success here wasn’t immediate. Flynn played at LSU from 2003-2007, where he redshirted his first year and then spent the next three holding on kicks and serving as JaMarcus Russell’s backup.

It wasn’t until 2007 that he finally became the starter, and he led LSU to the BCS National Championship by beating Ohio State 38-24 in the title game. Flynn was named the offensive MVP of the game and finished the season with 2,407 passing yards with 21 touchdowns and 11 interceptions.
