Jarrett Jack of the New Orleans Hornets is expected to miss at least a week with a sore left knee, according to the Associated Press.

After missing three games with the injury, the Hornets’ starting point guard attempted to make a return Wednesday night in a loss to the Chicago Bulls. Jack played nearly 28 minutes against the Bulls but racked up just four points and three assists; the team has since shut Jack down again.

Hornets coach Monty Williams says Greivis Vasquez will start in Jack’s place.

Eric Gordon (sore right knee), Carl Landry (sprained left knee) and Jason Smith (concussion) are all currently out for New Orleans as well. The Hornets are nursing the worst record in the Western Conference at 4-22.
