Although an ultrasound taken Wednesday shows progress in his torn left hamstring, Jordan Farmar will be sidelined for at least another week.

Farmar will be reevaluated on Dec. 24, which will officially pencil him out for at least three more games against Minnesota (Friday), at Golden State (Dec. 21) and at Phoenix (Dec. 23). It’s plausible Farmar could return when the Lakers host the Miami Heat Christmas Day at Staples Center, but that scenario seems unlikely considering he has said he needs at least a practice before playing in a game.

Farmar offered no assurances on his return date, but he sounded optimistic this week that he could’ve returned as early as Friday when the Lakers host the Minnesota Timberwolves at Staples Center had the test showed he was healthy enough to resume practicing. But the ultrasound showed his hamstring hasn’t fully healed, leaving the Lakers still without a traditional point guard.

Steve Nash had spent the past week during the Lakers’ five-day, four-game trip in Vancouver with his personal trainer Rick Celebrini rehabbing nerve issues in his back. Steve Blake will stay sidelined for at least five more weeks because of a torn ligament in his right elbow.

The Lakers (12-13) have sorely missed all three point guards, including Farmar, who average averaged a steady 9.2 points and 4.4 assists before missing the past seven games. Despite their depleting point guard depth, the Lakers don’t expect to add a point guard either through the free agency market or a trade. Instead, they will continue to delegate point guard duties to Kobe Bryant, Xavier Henry and Nick Young.
