Jets coach Rex Ryan said Wednesday that Turner will be operated on later this week to determine how long the versatile lineman will be sidelined. Turner was hurt during New York's 20-16 preseason-opening loss to the Texans on Monday night when Houston's J.J. Watt rolled into his leg.
"Certainly, that's unfortunate for us and we'll move on," Ryan said.
McKnight, also injured in the game, won't participate in team drills while he's being evaluated.
Meanwhile, wide receiver Plaxico Burress had his first significant practice as a member of the Jets after resting his sprained left ankle since Friday. Burress participated in a dozen team drills, the most practice he has had since signing with the team on July 31.
Linebacker Bart Scott (lower leg) didn't practice and will be monitored during the week.
Defensive lineman Sione Pouha didn't practice with a knee injury. Ryan was uncertain of the nature of the injury.
"I don't know what they call it, something on his knee," Ryan said. "But we put a brace on it and he was out there in pads, but he wasn't doing anything."
