Via Mike Petraglia of WEEI.com:
Monday was the 22nd straight game that Daniels missed following surgery on his left thumb. Initially, the Celtics didn’t anticipate his return until after the All-Star break, but if a checkup goes well on Tuesday, some basketball activities could be in the offing followed by practice, and then, games.
“We’ll find out more [Tuesday] about Marquis,” Rivers said. “We’re hoping first game after the All-Star break.
“There’s a slight chance he may be able to play by the New Orleans game [Feb. 10], which would be a huge benefit for him because he gets one game in before which helps him once we come out of break. We’re out of break on the West Coast, so we want to come out of break playing well.”
UPDATE: From Chris Forsberg... Quis was on the floor today.
Rivers also noted that Marquis Daniels participated in his first passing drills since having his cast removed. It's another step in the progress of Daniels, who might return in time for the New Orleans game before the All-Star break.
