The Houston Rockets have started the season in impressive fashion winning their opening two games against the Golden State Warriors and Sacramento Kings.

The only downside to those victories was the limited time Chris Paul was able to spend on the court as he followed up a 33-minute outing against the Warriors by sitting out of the Kings game.

The Rockets have now been dealt a big blow as the point guard could miss up to a month with a knee injury, according to Marc Stein of the New York Times.

Paul initially suffered the problem when he clashed knees with Memphis Grizzlies guard Mario Chalmers in pre-season.

He posted just four points, eight rebounds and 11 assists in the opening night win over Golden State but was clearly hobbled and sat out the majority of the fourth quarter.

The news will come as a blow to head coach Mike D'Antoni who is still looking to integrate CP3 with superstar James Harden.

In his absence, 'the Beard' is likely to assume point guard duties like he did last season and facilitate the team's offence.

According to reports, Houston is already looking to recruit a free agent to add cover for that position and one player who recently became available is veteran Jameer Nelson following his release by the Denver Nuggets.

The franchise is believed to have reached out to his representatives to discuss a possible deal.

But the Rockets are yet to comment on reports suggesting Paul could miss the next four weeks and have listed him as day-to-day.

But per Stein, they have already made it clear that they plan to be cautious with him as their goals are focused on the playoffs and making sure their stars are healthy in the latter stages of the season.

Speaking to reporters prior to tonight's encounter with the Dallas Mavericks - a game he's already been ruled out for - D'Antoni seemed to suggest that the injury wasn't a major concern.

“It’s only a bump,” D’Antoni said. “It’s not a tear or something like that. It’s a bruise. We just have to make sure he’s 100 percent the next time he plays.

“I don’t think there’s (concern.) All indications are he should be OK.”

The Texas-based outfit faces the Grizzlies in Houston on Monday before opening a three-game road trip.

“We’ll see on Monday,” D’Antoni said of getting his star back. “I think we’re shooting for that, but that doesn’t mean that. This time, we’re going to make sure it’s 100 percent and go from there.”
