Raymond Felton is already sidelined with a strained left hamstring, and the Knicks may now turn to Iman Shumpert -- and possibly Chris Smith -- to run the point.
"Pablo is a big loss," Carmelo Anthony said after the Knicks blew it in a 102-101 loss to the Washington Wizards by failing to foul or call a timeout in the final seconds.
Knicks coach Mike Woodson said he might turn to Shumpert, a natural wing player, to play some point beginning Wednesday in Milwaukee.
"I am ready for whatever but that is coach's decision," Shumpert said.
The Knicks also have Toure' Murry on the roster, but he has barely played.
Woodson also acknowledged it was possible the Knicks could recall Chris Smith -- who is on the roster -- from the D-League after Smith went for 28 points in a game on Saturday. Smith is J.R.'s younger brother and Woodson acknowledged in training camp that he was being given special consideration to make the team because of that.
"That's a possibility," Woodson said. "Again, we go and evaluate him [Tuesday] in terms of how he's been playing and we'll sit and talk about that, but that's a possibility as well."
Without Prigioni in the second half, Beno Udrih nearly engineered a victory by going for 12 points and five assists, but he was burned by Bradley Beal for a game-winning layup with 6.9 seconds left.
"There was absolutely nobody there," Beal said of the final play in which he drove right past Udrih and the Knicks brought no help defense.
The Knicks then failed to foul or call a timeout in the final seconds and Anthony let loose an errant 3-pointer as time expired.
"I probably should have taken the timeout at the end," Woodson said.
Said Anthony: "If he said it's his fault, then it's his fault. There's no need for me to talk about that or make excuses for it. If he said it was his fault and he take the blame, then he take the blame. I think as players we gotta be smart enough to know that as well, time, score and situation like that."
Anthony then added: "He's our coach and we're rolling with him."
