Darrelle Revis, four months removed from major knee surgery, could return to football-related activities in a couple of months, according to his personal defensive-back trainer.

Will Sullivan, who works out of the Arizona-based facility where Revis trains in the offseason, told the Star-Ledger of Newark the Jets' star cornerback is on schedule in his recovery. Once the medical people give the okay, Sullivan
will take the rehab to the field.

"For me, I think I’m thumbs up in April. I’m going to get the green light in April," Sullivan told the newspaper.

"The great thing is, there’s been no setbacks. It’s been a great surgery. He’s doing the right things. He hasn’t done too much, he hasn’t done too little. He’s doing just enough to make sure he’s cooperating with the doctor and physical therapist.

"Once I get the green light in April, it’s time to go hit it hard on the field, so I have to make sure we hit it in a progressive manner. ... With him I have to start off with level one. It’s all about how he graduates from program to program."

Sullivan has helped train Revis since he came out of Pitt in 2007. Sullivan said "you have to be careful with him" because of Revis' history of hamstring injuries, so they will take it slowly in the beginning. It'll start with short-distance sprints.

Sullivan said they give weekly updates to the Jets' medical staff. Revis, who tore his ACL in September, is expected to be ready for training camp in late July. The question is, will he be a Jet? His future will be one of the hottest stories in the league over the next several weeks.
