Tonyan signed with the Vikings' practice squad Wednesday, Kevin Seifert of ESPN.com reports.

EDGE Analysis

Tonyan was diagnosed with back spasms in late July, which held him out of practices and all three of the Vikings' preseason games. With T.J. Hockenson (knee) starting the regular season on the PUP list and Nick Muse dealing with an undisclosed injury, Tonyan -- if healthy -- could be elevated to the active roster to provide tight end depth behind Josh Oliver and Johnny Mundt for Week 1 against the Giants.
