(Sports Network) - The San Antonio Spurs will have to continue their playoff push tonight against the New York Knicks without star guard Tony Parker.

The team did receive some good news on Monday, however, when it was learned that Parker won't need surgery for a broken bone in his right hand. An examination of the All-Star confirmed an initial diagnosis of a non-displaced stable fracture of the right fourth metacarpal and Parker is still expected to be sidelined for about six weeks, which likely means he will not return until the postseason.

Parker, the Spurs' second-leading scorer this season at 16.5 points per game, originally suffered the injury late in the first half of last Saturday's 102-92 win over the Memphis Grizzlies.

Without him, San Antonio fell in Cleveland on Monday when Mo Williams had 17 points, eight rebounds and eight assists, as the Cavaliers edged the Spurs, 97-95, despite playing without LeBron James and Shaquille O'Neal.

Manu Ginobili had a huge night for the Spurs, sinking seven three-pointers on his way to 38 points. He appeared to hit a game-tying three with 14.2 seconds left, but it was ruled a two-pointer after review.

George Hill added 23 points for San Antonio, which had its four-game win streak broken.

"We had a great opportunity, not many teams can come in here and win," Ginobili said. "LeBron wasn't playing, Shaq wasn't there [because of thumb surgery] and [Antawn] Jamison didn't play the second half, so we blew a big one, so we are kind of upset with that."

The Spurs currently sit in seventh place in the Western Conference playoff race, a still comfortable 4 1/2 games ahead of ninth-place Memphis.

The Knicks, meanwhile, are playing out the string but are coming off an exciting 99-98 win over playoff-bound Atlanta on Monday. Danilo Gallinari made four three-pointers and finished with a game-high 27 points in that one, as New York escaped with the victory at Madison Square Garden.

David Lee contributed a double-double with 19 points and 13 rebounds, while Al Harrington went for 14 points off the bench for the Knicks, who were able to recover from a 113-93 loss to New Jersey on Saturday.

"I thought our team the whole game did a good job competing on the boards, did a good job competing for loose balls," Lee said. "We did a good job overall."

New York, which had lost four of its last five coming into the contest, made 10-of-15 three-pointers after setting an NBA record by going 0-for-18 from three-point range in the setback to the Nets.

The Spurs have won eight of their past nine meetings with the Knicks, including a 95-88 win in New York earlier this season. San Antonio has also won six straight over the Knicks in the Alamo City.
