Celtics  coach Doc Rivers  said his head trainer Ed Lacerte told him hours before Friday’s tip-off that Rajon Rondo  wouldn’t be available to the team in their game against Chicago because of lingering soreness in his left foot.
“[Friday] morning, Eddie told me that Rondo wasn’t playing because of his foot,” Rivers said after Friday’s overtime game in which Rondo played 41 minutes, scored 10 points and dished out 11 assists. “And ten minutes later I go down so we can watch film and Rondo said, ‘I’m playing; I’m fine.’”
Asked if Rondo was dealing with plantar fascitis, Rivers said, “I think that’s what it is, and it’s a mild case but when those get fired up, those are extremely painful.”
But Rivers was impressed with the way Rondo managed himself through pain on Friday.
“Down the stretch, his defense, his hands ‘ the steal on the in-bounds play, the deflection steal at the end of the game on the last shot,” Rivers said. “He was great. I mean, [Derrick] Rose  got one drive in the over time and he yells to the bench, ‘My fault!’ He was just ‘ he was locked in tonight. And that’s what we need.
‘I told him that before the game, too. I walked right over to him before the tip and said, ‘Hey, listen, if I see anything’¦’ You could see he was good. The only thing we did and you could tell: we subbed him early. I think with five or six minutes in the first we subbed him. And then we did it again at half time. And overall that may have helped him with his wind.’
Rondo took treatment for 30 minutes after the game and then said he has been dealing with pain in both feet, with more pain in his left foot. He also said he’s been sleeping with both feet elevated to relieve the soreness.
