Anthony Randolph to miss time

TORONTO -- Anthony Randolph was walking with the aid of crutches Wednesday morning as the New York Knicks held their shootaround prior to their season opener against the Raptors, and said the ankle he sprained Tuesday should only keep him sidelined for a week at most.

However, a statement issued later in the day by the team said Randolph was re-evaluated in the afternoon and is expected to miss about two weeks.

Randolph's injury, sustained when he landed on a teammate's foot at practice, had the potential to exacerbate one of the Knicks' biggest weaknesses from the preseason -- their propensity to get outrebounded. Their opponents grabbed an average of 12.1 more rebounds per game in eight preseason games.

The 21-year-old Randolph had been penciled in as the backup power forward, a role that will now temporarily fall to Wilson Chandler in his new role as a reserve.

Chandler was the Knicks' starting two-guard last season, but that job has now been handed to rookie Landry Fields, the second-round pick from Stanford who led the Pac-10 in scoring and rebounding last season.

"I'm feeling much better today than I did yesterday," said Randolph, who missed the final 47 games of last season with torn ligaments in his left ankle -- the same one he re-injured Tuesday. "It wasn't as bad as it could have been. The other injury is healed up fine. It's healthy."

Coach Mike D'Antoni's elevation of Landry into the starting five was the most surprising news to come out of the final portion of training camp. He averaged 8.6 points and 2.9 rebounds in the preseason, shooting 59 percent, and was given the starting nod after D'Antoni toyed with the idea of using Toney Douglas alongside Raymond Felton in an alignment of two pure point guards.

"If Wilson was starting and got into foul trouble, we would be a little bit behind [depth-wise]. But Wilson will be able to spell the 4 and the 3, so there are different reasons why you want to start Landry, and that would be one of them," D'Antoni said.

With Randolph inactive, Shawne Williams was expected to be on the active list for Wednesday's opener.

Also, D'Antoni pronounced rookie Timofey Mozgov "100 percent" a day after the 7-foot-1 center bruised his hip at practice.
