Harris was at his usual inside linebacker spot in early drills Thursday and wasn't noticeably hobbled. Harris said his ankle felt "kind of stiff," but he hopes to play in Saturday's AFC wild-card playoff game at Cincinnati.
"I've been out here all day getting treatment and doing rehab and everything I can to get back out there on the field," Harris said. "Hopefully, I'll be fine by Saturday."
"I thought it was an illegal hit," said Harris, who added that it was a chop block. "Obviously, they didn't throw the penalty on it, but it put me out."
"It puts you in an awkward and dangerous position when you get high-lowed like that," Harris said, "and I don't think it was a fair shot."
Harris, who's in his third NFL season, worked on his footwork and agility while pushing off the ankle at times at practice. His status for the game will not be known until the Jets' final injury report is released Friday.
"David wasn't a full-go by any stretch of the imagination, but I think it was an encouraging sign, the fact he was able to get out there and do something," Ryan said. "So we'll see how that goes."
Harris also responded to Bengals running back Cedric Benson's comments this week that he doesn't "even really know who that is."
"I'm only the leading tackler on the No. 1 defense," Harris said. "It's hard to not know who I am. ... If I play, I'm sure I'll introduce myself early to him."
