FLORHAM PARK, N.J. -- Rex Ryan was not ready to declare tight end Dustin Keller ready for action Sunday when the Jets host San Francisco at MetLife Stadium.
"We'll find out," Ryan said.
Keller, one of the favorite targets of quarterback Mark Sanchez, missed two games with an injured hamstring. Keller participated in team drills with the Jets on Friday, but was not available in the locker room after practice.
Ryan said Keller hadn't faced another setback.
Ryan was not as optimistic about wide receiver Stephen Hill, who also has a hamstring injury.
"Don't anticipate him playing," Ryan said.
Out: CB Darrelle Revis (knee).
Doubtful: WR Stephen Hill (hamstring).
Probable: DT Sione Po'uha (low back), Isaiah Trufant (ankle), CB Antonio Cromartie (shoulder), LB Nick Bellore (shoulder), QB Mark Sanchez (low back), C Nick Mangold (wrist), LB Calvin Pace (Achilles), Mike DeVito (calf), Brandon Moore (hip), CB Ellis Lankster (low back), Matt Slauson (knee), LaRon Landry (heel), Eric Smith (hip knee), Austin Howard (low back).
