Thompson is sent down to AHL Rochester while at the middle of a 23-game goal drought. The 22-year-old has just seven goals and five assists for 12 points in 65 games this season.
Thompson’s demotion on Thursday comes each day after Buffalo called up rookie forward Victor Olofsson.
Olofsson is leading Rochester using 60 points. He’s got a way to create his NHL debut Thursday, when Buffalo hosts Detroit.
