FLORHAM PARK, N.J. -- Dustin Keller will miss a second day of practice with an ankle sprain, coach Rex Ryan said before heading out to the field. The tight end’s odds of playing became less likely although Ryan would not yet rule him out against Jacksonville on Sunday.

"I know he is getting better, so we'll see how it goes," Ryan said. "Not willing to rule him out certainly but this is the second day that he's missed. But I know he's getting substantially better."

The Jets receiver corps is looking pretty thin. WR Clyde Gates (concussion) also isn’t practicing, but Ryan was optimistic that he could be back next week. S Laron Landry will take the day off with his heel injury, which is part of the safety’s usual routine.

Ryan has also not yet decided between Greg McElroy and Tim Tebow for the No. 2 quarterback spot. He said Tebow practiced more on Wednesday but wasn’t ready to make the call. He did say Tebow would travel with the team even if he doesn’t dress for the game.

Tebow was projected to be limited, along with WR Stephen Hill (knee), RB Joe McKnight (ankle/ribs), DL Sione Pouha (lower back) and OL Brandon Moore (hip).

As for the rest of the injury report, these players are projected to practice fully: NT Kenrick Ellis (knee/lowback), RB Bilal Powell (shoulder), QB Mark Sanchez (low back), OL Slauson knee), TE Jeff Cumberland (wrist), LB Calvin Pace (shoulder), C Nick Mangold (shoulder), WR Jeremy Kerley (heel/hamstring), LB Bart Scott (toe), CB Aaron Berry (quad), LB Ricky Sapp (ankle), DE Mike DeVito (shin), FB Lex Hilliard (finger) and WR Chaz Schilens (knee).

Given the shorter days, Ryan has moved up the schedule and condensed practice so that it can be completed before the light fades.
