Zach Wilson traveled to Los Angeles and will undergo surgery on his knee Tuesday, according to Jets coach Robert Saleh, who is withholding declarations of a quick recovery. “They’ll know more when they get in there,” Saleh said. “We’re optimistic but we’re not out of the woods until they get in there and make the decision.” The optimistic recovery timeline is 2-to-4 weeks after Wilson tore his meniscus in Friday’s preseason opener against the Eagles, the result of a hard cut on his right leg during a scramble. Although the Jets avoided a worse-case scenario of an ACL tear, the fact that their franchise quarterback is going under the knife is discouraging.
