"I was able to take the whole summer off and let my body heal," Garrard said, according to the Jets' official website. "I started training a couple of months ago and my knee feels great.
"I'm sitting at home, watching games thinking, 'Why am I at home? Why I am doing this to myself? I didn't want to have any regrets one day."
Rex Ryan told reporters Thursday that Garrard contacted general manager John Idzik over the weekend. Ryan presented Garrard's situation as a two-week tryout.
"There's not been any guarantees or promises made," Ryan said.
