Reisner originally signed with the Vikings as an undrafted free agent following the NFL lockout in 2011 and spent part of two seasons with the NFC North club.
He was claimed by the Jacksonville Jaguars off waivers in 2012.
He was placed on injured reserve designated to return by the Jaguars last year before returning to the Jaguars' active roster in December.
He caught five passes for 40 yards last season in five games with three starts. He has seven catches for 58 yards for his career in four NFL seasons.
