The Spurs hope to have Tim Duncan back in the lineup as they go for their seventh straight win at home - and fifth in a row overall - on Friday night in their first meeting with the Eastern Conference-leading Cavaliers.

Duncan has missed San Antonio's last two games because of right quad tendonosis, and he's day-to-day. Spurs coach Gregg Popovich said Wednesday the team would have to wait and see if Duncan's healthy enough to play against the Cavaliers.

"(Tuesday) night he had no strength in his leg," Popovich said. "It's not quite as bad today."

The Spurs (39-17) were already without Manu Ginobili, who hasn't played since the All-Star break because of a stress reaction in his right ankle and is expected to miss at least one more week.

Without two-thirds of the trio that has led the Spurs to three NBA titles in six years, Parker has been San Antonio's top offensive option. He had 37 points and 12 assists in a 93-76 win over Dallas on Tuesday, then scored 39 with nine assists in a 99-84 victory over Portland the following night.

"Tony Parker was a super stud again, and generated the offense again," Popovich said. "His leadership on the floor was exceptional."

In the two games without Duncan, Parker has shot 54.2 percent (32-for-59) from the field while totaling 72 minutes.

"I prepared myself today," Parker said Wednesday. "I drank a lot of water. ... I knew (Duncan) was not going to play, so I prepared myself to play 40 minutes."

While Parker has managed to carry the Spurs lately, keeping the home winning streak alive will probably be more challenging against the Cavaliers, one of the NBA's best road teams at 18-11.

However, Cleveland (44-12) delivered a flat offensive performance in a 93-74 loss at Houston on Thursday in the opener of a four-game trip. The Cavaliers recorded season lows in points, field-goal percentage (33.8) and assists (10).

LeBron James, perhaps the league's leading MVP candidate, was held without an assist for the first time in 493 career games, including the postseason.

"I'm not happy with that at all," said James, who had 21 points and went 7-for-21 from the field. "I can't remember the last time I didn't have an assist, but as a team, we didn't move the ball at all. We'll just move on to the next game."

Cleveland has done a very good job of that so far. It's 9-2 in the second half of back-to-backs and 10-1 in games following a loss.

While Duncan's status is uncertain, the Cavaliers know they'll be without their top interior defender for a while. Ben Wallace broke his right leg Thursday and will be sidelined four to six weeks.

"It's a tough blow for us," said coach Mike Brown, whose team passed up chances to acquire a big man before the trade deadline. "We just have to have somebody step up and play some quality minutes for us."

The Cavaliers and Spurs split two games last season, their first meetings since San Antonio swept Cleveland in the 2007 finals.

James had 27 points, nine rebounds and seven assists in a 90-88 win in San Antonio on Jan. 17, 2008. He had 39 in the clubs' next game, but was outdone by Ginobili's 46 in the Spurs' 112-105 road victory Feb. 13.

James is averaging 31.4 points and shooting 51.2 percent in five career wins over the Spurs. He's been held to 23.1 points and 40.9 percent shooting in nine losses, including the playoffs.
