WALTHAM, Mass. -- Celtics forward Jeff Green (sprained right knee) and forward/center Chris Wilcox (illness) did not practice Thursday and both are questionable for Friday's visit from the Portland Trail Blazers.
Boston is also awaiting word on the fate of Rajon Rondo, who could be suspended for his part in a dust-up with Kris Humphries that left both players ejected from the Nets' win Wednesday at TD Garden.
"There's a chance there's no Wilcox tomorrow, there's a chance there's no Jeff Green tomorrow," said Rivers. "So, they're checking a lot of things. But, I don't care who doesn't play. The guys that play, we have to be ready to play and ready to win."
Green tweaked his knee in the third quarter of Wednesday's game, but returned to action. It flared again overnight, forcing him to be a spectator at Thursday's practice. Wilcox was not spotted as he battles flu-like symptoms.
If shorthanded due to injury, Rivers said the team would consider recalling Kris Joseph and/or Fab Melo from the D-League. In need of frontcourt depth, the Celtics would consider the rookies on assignment with the Maine Red Claws.
"Well, we might have to [call them up]," said Rivers. "But it doesn't matter. Now, if they are unavailable from injury, yeah, we can bring them in. If it's because of Rondo or somebody else gets suspended, you can't replace those players on your roster."
If Rondo is ultimately suspended, Rivers said he would lean on the three-guard rotation of Jason Terry, Courtney Lee, and Leandro Barbosa to split ball-handling duties. Regardless of the severity of any penalty, Rivers hinted the team remains in no rush to make a move to add a pure ball-handler. And Boston's overall struggles have left Rivers no less inclined to make a roster move at any position.
"If there's somebody out there, we're obviously going to bring him in," said Rivers. "But we're in no rush. We're not going to overreact to the way we're playing. We're not playing well. Let's not overreact to it by trading the team or changing guys. Let's see if we can get this right first."
