The Vikings plan to activate Smith (ankle) from injured reserve before Sunday's game against Chicago, Tom Pelissero of NFL Network reports.
Smith will return as the team's No. 2 tight end, behind trade-deadline addition T.J. Hockenson, with the talented duo potentially inspiring head coach Kevin O'Connell to use more two-tight end sets and fewer looks with three wide receivers and/or fullback C.J. Ham. However it plays out, Smith was designated to return from IR last week and apparently will make it back for the final game of the regular season as a tuneup for the playoffs.
