SAN ANTONIO -- Celtics center Nenad Krstic suffered a right knee injury after it bent awkwardly as Krstic drove toward the basket late in the first half Thursday night against the Spurs.
According to the Celtics, Krstic will not return.
Krstic grimaced before collapsing beneath the basket and clutching the knee in pain. He eventually got to his feet and hobbled to the locker room with the aid of team trainer Ed Lacerte.
The Celtics got one center back on Thursday in Jermaine O'Neal, who had been sidelined since Jan. 12 following left knee surgery, and are hoping to get another, Shaquille O'Neal, who has been sidelined since Feb. 1, back as early as next week.
Krstic has been the team's starting center since being acquired in the deal that sent Kendrick Perkins to Oklahoma City at the trade deadline in late February.
UPDATE: Krstic will undergo an MRI in Boston on Saturday and Celtics coach Doc Rivers said he will not play Friday against the Hawks or Sunday versus the Pistons. Click HERE for more on the injury.
