Carmelo Anthony is injured again.

The New York Knicks star small forward -- who has kept them from bombing during the first stretch of the lockout-shortened NBA season -- was back on the bench Thursday night after spraining his right ankle in the second half of the team's 94-83 loss to the Memphis Grizzlies at the FedExForum.

The four-time NBA All-Star player rolled his ankle while competing for a loose ball with Memphis center Marc Gasol. The forward limped off the court with 10:05 minutes left in the third quarter, and did not return. Earlier in the contest, Anthony -- who came into the game with both a sore left knee and a sore back, the latter hurt against the Washington Wizards in a road win on Jan. 6 -- also injured his left wrist.

New York's loss was its first after a four-game winning streak, but its full impact on the Knicks has not been determined yet, as the organization had not announced as of Thursday night just how long the star will be sidelined.

Results of X-rays taken of Anthony in Memphis were negative, but his status for New York's road game against the Oklahoma City Thunder on Saturday had not been released as of Thursday night, according to the New York Daily News.

Despite the Knicks' recent winning streak, the team has had a rocky start in its first full year with Anthony on the roster. Other additions to the regular rotation this season are veteran center Tyson Chandler and rookie guard Iman Shumpert.

Before Anthony's injury on Thursday, he scored 14 points, a club-leading figure matched by teammate Bill Walker. However, Amar'e Stoudamire did not do well, as the star power forward scored just six points while making only one of seven field-goal attempts. Meanwhile, Shumpert netted 12 points on five-for-20 shooting from the floor.
