Both moves were made Monday, with Buffalo in the midst of a 1-9-2 skid. In exchange for Wilson, the Red Wings acquired Buffalo’s fifth-round pick in the 2015 draft.
Detroit initially acquired Wilson in a trade with Pittsburgh on Oct. 21. He has no points in 20 games this season and 13 goals and 32 points in 123 career NHL games. Wilson did have three goals and six points in 20 playoff games in helping the Penguins win their second consecutive Stanley Cup last season.
Moulson, 34, will be assigned to the minors should he clear waivers Tuesday. He has no points in 14 games and has been a healthy scratch in seven of Buffalo’s past nine outings.
He is an 11-year veteran who is in the fourth year of a $25 million contract. The demotion leaves Moulson’s long-term future with the Sabres uncertain, though he’s due to make $5 million next season.
The Sabres also recalled forward Evan Rodrigues from the minors in preparation to play at Colorado on Tuesday.
