The moves were announced on Tuesday.
Wilson, who appeared in 10 games last season, broke his collarbone in training camp. He will miss the first eight weeks and will not be eligible to play until Nov. 9, when the Bears visit Green Bay after their bye.
With Wilson out, the Bears brought in veteran Santonio Holmes. He figures to be the No. 3 receiver.
Hayden was released by the Bears on Saturday as they trimmed their roster to 53. He missed last season because of a torn hamstring after appearing in 16 games in 2012.
