Point guard Shaun Livingston is scheduled for another checkup in Alabama next week to test the progress of his injured left knee.

If everything checks out with Dr. James Andrews, who is considered one of the nation's top orthopedic surgeons, Livingston will move on to the next phase of his rehabilitation: regaining the explosiveness in his left knee that he had before his gruesome February injury when he tore three ligaments and dislocated a kneecap.

"It'll be trying to get that back," Livingston said. "The explosion. Really planting off and jumping on it."

Livingston is still hoping to resume practice with the team in February with a possible return the next month. He is fitted with a custom-made knee brace and has traveled with the team the last month.

Los Angeles Clippers' forward Tim Thomas underwent an MRI on his left knee today. The results, which were reviewed by team physician Dr. Tony Daly, were negative. Thomas is listed as day-to-day with a sore left knee. Thomas originally injured the knee in the 1st quarter of the Clippers? game in San Antonio on Saturday night.

In 25 games this season, Thomas has averaged 12.6 points and 5.2 rebounds per game.

Reserve forward Paul Davis sustained a season-ending injury -- a torn ligament in his right knee -- in Friday's loss to the Dallas Mavericks.

Davis landed awkwardly on the leg while deflecting the ball off the Mavericks' Erick Dampier in the second quarter and stayed on the ground for several moments before being helped off the court.

The injury was originally diagnosed as a sprain, but afterward Davis said, "I definitely never felt anything like that before."

An MRI in Los Angeles on Saturday performed by team physician Dr. Tony Daly revealed the extent of the injury.

He sustained a torn anterior cruciate ligament, a stabilizing ligament within the center of the knee, and also tore his lateral meniscus (cartilage around the knee). He is scheduled to meet with Daly again Monday and his surgery will probably take place within 10 days once the swelling in his leg subsides.

"He has worked hard, and this was the year he was getting an opportunity to play and the last couple of games he was playing well for us," Coach Mike Dunleavy said. "Hopefully, he has a speedy recovery and bounces back."

Clippers' forward Tim Thomas and Spurs' guard Manu Ginobili were injured during the first quarter of their game Saturday night.

Thomas fell to the ground and was in obvious pain after appearing to get tripped up by another Los Angeles' player. He was helped off the floor with 6:38 to play in the first and, the team said he had a sprained left knee.

With about 4 1/2 minutes to go in the first, Ginobili grabbed his left hand and left the court. The team said he sprained his left index finger. It's the same injury Ginobili had Dec. 2 against Portland.

According to a report in Sports Illustrated, Clippers' guard Sam Cassell's name has popped up several times in regards to players rumored to be traded before the Feb. 21 trade deadline. No specific teams, however, were mentioned.

A prime reason why Cassell is attractive trade bait is because with his experience and ability; he would be a solid addition to a team vying to go deep in the playoffs. Just as importantly, the 38-year old Cassell has an expiring contract.

"I haven't heard anything, but I'd like to be here," Cassell said. "But if something happens, that's just part of this business and I can't cry about it."

Elton Brand stood near a basket, then jumped off both feet ever so slightly while shooting a hook shot.

The Clippers' franchise forward, who ruptured his left Achilles' tendon in the off-season is still months away from game action, but Monday was the first time Brand has left his feet since the injury.

"It felt good," Brand said. "Light jump shots, shooting, ballhandling, defensive slides earlier. Everything was real low impact. It was a big step for me today."

"To be semi-in practice, it was an important step."

Brand also walked and did light jogging on a treadmill for 20 minutes and will look to increase that as his Achilles heals.

"Seeing [injured guard] Shaun [Livingston] out here shooting the ball and doing stuff and E.B. starting to do the same, yeah it's good," Coach Mike Dunleavy said. "No question."

The Los Angeles Clippers today signed free agent guard Richie Frahm. Per team policy, terms of the deal were not released.

Frahm was most recently on the Phoenix Suns' roster for the 2007 preseason before being waived on October 24. The 6-foot-5, 202 pound three-point specialist has averaged 3.5 points, 1.2 rebounds and 0.6 assists in 130 career games with the Houston Rockets, Minnesota Timberwolves, Portland Trailblazers and Seattle Supersonics.

Frahm played for Italy?s Benetton Treviso in 2006-07 after appearing in a total of 32 games for the Timberwolves and Rockets in 2005-06, averaging 3.4 points.

Injured forward Elton Brand received clearance to begin dribbling and taking stationary shots after a recent checkup at the Delaware facility where he had his ruptured Achilles' tendon surgically repaired.

Brand, the Clippers' franchise player who is recovering from the injury sustained in the off-season, is set to start the activities on Monday, according to Dr. Craig Morgan of Christiana Care's Wilmington Hospital.

"We are pretty much still with the original plan," said Morgan, who performed Brand's surgery. "The rest of his rehabilitation is going to be getting his strength back."

Brand has said he is optimistically targeting February as a return month.
