From Angelo State, Josh Neiswander signed with the Montreal Alouettes in 2012. Neiswander didn't see much action in his rookie season bhend Anthony Calvillo and Adrian MacPherson at querterback, but moved up to the backup spot on the depth chart in 2013 with the release of MacPherson. When Calvillo was knocked out of game 7 against Saskatchewan in 2013, Neiswander finished the game and played creditibly in a losing cause. With Calvillo still out in game 8 agaisnt BC, Neiwwander got his first start in the CFL, but was pulled in tghe first quarter in favour of Tanner Marsh.
