Muzzin (upper body) will visit a doctor Tuesday and is expected to receive clearance to play Thursday against the Sabres, Lisa Dillman of the Los Angeles Times reports. Muzzin has been sidelined for the Kings' first six games with the upper-body injury, with the team giving no clear timetable for the blueliner's return until now. The Kings have resisted putting Muzzin on injured reserve while he dealt with the ailment, so no roster move will be required to bring him back in the fold. He's expected to rejoin the team's top pairing with Drew Doughty.
