Kessel learned he had cancer shortly before playing in a Dec. 9 game against New Jersey. He underwent surgery three days later to remove his right testicle.
He played two games last week for Providence of the AHL, scoring in a 2-1 loss Saturday to the Manchester Monarchs.
Kessel has appeared in 27 games for Boston this season – his last against New Jersey – scoring five goals.
The Bruins also recalled goalie Philippe Sauve and assigned centre Yan Stastny and goalie Hannu Toivonen to Providence of the AHL.
Sauve has played in two games for Boston this season, earning no decisions in relief.
Toivonen was recalled from Providence before Boston’s 4-3 win Saturday over Philadelphia, but did not play. He has played in 10 games for the Bruins this season, posting a 2-5-0 record.
Stastny has played 20 games for the Bruins, making two assists.
