The Steelers signed Brian Arnfelt to their 53-man roster from their practice squad Saturday and released linebacker Kion Wilson.
Arnfelt, who will wear No. 69, signed April 27 as an undrafted rookie. He was released Aug. 31 and signed one day later to their practice squad, where he has been all season.
Wilson played in seven games this season and started two at inside linebacker after Larry Foote was injured in the opener. This is the second time he has been cut this season.
