Celtics  coach Doc Rivers  said Paul Pierce  continued his cardio workout on Friday but is still unsure whether the team’s captain will be able to return on Sunday for the showdown with the Orlando Magic  at TD Garden.
“It’s day-to-day,” Rivers said of Pierce’s left mid-foot strain. “That’s about it, really. He’s moving around, shooting around a little bit. I don’t know yet.”
Marquis Daniels , meanwhile, will practice again on Saturday but Rivers said there’s still no guarantee he’ll be ready to play against Orlando. Rivers’ main concern is not the thumb but rather the ability of Daniels to run the team’s offensive sets that have been installed since he last played on Dec. 4.
“I’m not so sure about him on Sunday.” Rivers, whether Daniels will be prepared to return. “We’ll have to throw him in eventually.”
For Daniels, it’s his 28th straight game missed following ligament surgery on his left thumb.

“Really, I didn’t know that,” Rivers said . “That’s unbelievable. You Boston guys [media], I thought you were tough. That’s surprising. They’re some guys out there that clearly should be doing this a lot longer than me. You know how this league is – it’s a talent-based league. If you have enough of it and do your job with it, then you stay.
The pregame discussion ended with his thoughts on Sunday’s big game between Indianapolis and New Orleans.
“Super Bowl  predictions?,” Rivers said, repeating the question asked of him. “The Saints, what the [heck]. No reason for that. Maybe the reason is I’ve heard about Colts. I wondered if [the Colts] were playing anybody so I’m going with the other team.”
