Cincinnati Bengals linebacker Vontaze Burfict, running back Joe Mixon and cornerback Dre Kirkpatrick all are expected to play Sunday against Detroit.
All three have been out since suffering concussions Dec. 4 against Pittsburgh.
Mixon returned to practice last week but was unable to clear protocol in time for the game at Minnesota. Burfict and Kirkpatrick returned to practice this week. None of them are listed on injury report for the season finale against the Lions.
Safety George Iloka (shoulder) is questionable, and starting left tackle Cedric Ogbuehi (shoulder) is out.
Also Friday, the Bengals placed linebacker Nick Vigil on season-ending Injured Reserve due to a back injury. Vigil missed the last three games with an ankle injury.
To fill Vigil’s spot on the 53-man roster, the Bengals promoted Kent Perkins from the practice squad. Perkins, a 6-foot-5, 320-pound rookie from Texas, signed as an undrafted college free agent in the spring and has been on the practice squad all season.
