FLORHAM PARK, N.J. - Jets rookie Devin Smith is expected to miss four to six weeks with broken ribs, according to coach Todd Bowles.

According to the team, Smith also suffered a partially punctured lung, but his timetable for return won't change. The Jets said he'll spend a second straight night in the hospital.

The former Ohio State speedster was injured during Friday's practice when he was hit from behind by cornerback Jaiquawn Jarrett as he came down with a tough catch on the sideline.

The Jets later announced that Smith had suffered broken ribs on the play. But it wasn't until Saturday that his minor lung injury was disclosed.

Bowles called it "a freak accident."

"That was extremely tough [to see]," quarterback Geno Smith said. "He had just made a great play and everyone was praising him because Devin is a guy who can make plays like that. And to see him get hurt, obviously, he's a guy we expect to play and do well."

Right guard Willie Colon (left knee) was activated off the active/PUP list . . . Cornerback Dee Milliner (Achilles) also practiced for the first time . . . General manager Mike Maccagnan confirmed that the Jets have had talks with the agent for Evan Mathis, but he didn't sound optimistic about landing the two-time Pro Bowl guard. "Obviously, Evan's a good player," he said of the 33-year-old, who was released by the Eagles in June. "As this thing plays out a little bit, we'll kind of get a better feel for that . . . Evan may have a value he's looking for right now that may not be the value that some of the teams want to potentially spend on him." . . . Maccagnan also is steering clear of the Jets' quarterback decision. "First and foremost, Todd makes the decision on the depth chart and who starts," Maccagnan said. "He'll know my opinions and input, but, at the end of the day, that's Todd's decision."
