Cornerback Darrelle Revis was limited at practice Wednesday while recovering from a concussion suffered in the New York Jets' season opener.
Revis was cleared for practice and took part in some position and individual drills, but still can't be involved in any contact. Revis missed the Jets' game at Pittsburgh on Sunday after suffering what the team called a "minor concussion." He said last week that he was in "a fog" after he was first hurt, but has gotten progressively better since.
His status for the team's game at Miami on Sunday is still uncertain.
Revis needs to be cleared by the team physician and an independent neurological consultant in order to practice with full contact and then play.
"We'll see how he progresses," Ryan said.
Revis, who speaks to the media almost daily, politely declined to chat Wednesday.
Quarterback Mark Sanchez was on the injury report with tightness in his lower back, but Ryan said he didn't think it was serious. Sanchez, who said he was fine, was a full participant at practice and didn't appear at all hampered.
Tight end Dustin Keller did not participate in practice with a hamstring injury that also sidelined him against the Steelers.
"It felt pretty good today," Keller said. "I feel good, and I feel like I'll be out there and be part of the game plan, but we'll see. I didn't get to go out there and get the live reps today, so tomorrow will be a big opportunity for me."
Keller injured his right hamstring in the Jets' second preseason game against Carolina, and then tweaked it again during practice last Wednesday. He said it was initially diagnosed as somewhere between a Grade I and Grade II strain.
His absence was particularly noticeable midway through the game against Pittsburgh when Sanchez struggled to find an open receiver. Keller has led the Jets in receptions each of the last two seasons.
Fullback John Conner (right knee), linebacker Bryan Thomas (hamstring) and safety Eric Smith (hip, knee) were also not going to practice. Nose tackle Sione Po'uha and defensive back Ellis Lankster were both limited with lower back issues.
