As Richard Hamilton returned to shooting drills on a light practice day, C.J. Watson ditched the sling he had been wearing to protect his sprained left elbow. However, as Watson left the Berto Center to undergo a Monday afternoon MRI exam, coach Tom Thibodeau said it's likely Watson will miss Tuesday's home game against the Atlanta Hawks. "That would be my guess," Thibodeau said. "It's a sprain. (Athletic trainer) Fred (Tedeschi) saw him this morning and the swelling isn't too bad. He'll be day-to-day basically."
