West, who has bounced in and out of the rotation all season, missed Tuesday's win at Detroit with what the team called a sprained left knee. He is averaging 8.6 points and 3.1 assists as a reserve this season.
Shaquille O'Neal has rejoined the Cavaliers as well. O'Neal, who has been at home in Florida, is expected to miss the rest of the regular season following surgery to repair his right thumb. He injured it in a win at Boston on Feb. 25.
