Toussaint will reprise his role as a depth option behind star back Le'Veon Bell and 2017 third-rounder James Conner. In limited work with the Steelers last season, Toussaint carried six times for 25 yards and added two catches for nine yards, while suiting up for six games.
Toussaint has cleared the league's concussion protocol and will be able to return to Sunday's game against the Jaguars, Ed Bouchette of the Pittsburgh Post-Gazette reports.
Toussaint will be able to return kicks in the second half of Sunday's contest for the Steelers if need be, but he likely won't see much action out of the backfield with Le'Veon Bell at full health.
Toussaint is being evaluated for a possible concussion and his return to Sunday's contest against the Jaguars is questionable.
Toussaint's potential absence could result in additional kick-return opportunities for JuJu Smith-Schuster, but the backfield will continue to be led by Le'Veon Bell per usual.
Toussaint, who ran for 22 yards on five carries, and caught two passes (on three targets) for nine yards in Sunday's win over the Browns, finishes up the 2017 season with 25 yards on six carries and the two receptions in six games.
Toussaint added 35 yards on two kick returns, giving him 94 yards on six kick returns. An unrestricted free agent, he may be challenged for a roster spot next season by Stevan Ridley.
Bell could still dress for the Week 17 game given that the team only has three healthy tailbacks on the roster, but the Steelers' reluctance to expose him to injury heading into the postseason will likely leave either Stevan Ridley or Toussaint on hand to absorb all of the touches out of the backfield. After earning nine carries to Toussaint's zero in the 34-6 win over the Texans in Week 16, Ridley looks positioned to see the larger portion of the workload, but Toussaint should see an enhanced opportunity nonetheless. Expect most of the snaps Toussaint receives to come on clear passing downs or when Ridley needs a breather.
