FLORHAM PARK, N.J. - The hits just keep on coming for the Jets' secondary -- and not the good kind.
Hours after the Jets waived injured safety Antonio Allen, who has a torn Achilles tendon, they announced that cornerback Dee Milliner underwent surgery on Friday after suffering a wrist injury during Thursday's practice. He's expected to miss six to eight weeks.

Milliner, the ninth overall pick in the 2013 draft, has an extensive injury history. This latest procedure is the seventh surgery for the former Alabama star.
Milliner has played a total of only 16 games in two seasons, but coach Todd Bowles said he's not worried about Milliner's durability.
"I'm just getting to know him," he said, adding that Milliner initially thought it was only a sprained wrist and kept practicing. X-rays revealed tendon damage and a bone that went out of place. "Being a rookie and coming in and getting hurt for a year and a half, a lot of guys have done that and have gotten over it. A lot of guys haven't. So you've got to wait and see."
Before being drafted, Milliner underwent five procedures, including shoulder surgery after his senior season that forced him to miss much of the 2013 season. Last year, he suffered a high ankle sprain in training camp and tore his right Achilles tendon on a special-teams play against the Broncos on Oct. 12.
"Some guys just bite the injury bug," Bowles said before highlighting Milliner's "mental toughness."
Allen, who suffered the non-contact injury in Thursday's practice, could end up on injured reserve if he clears waivers. The 26-year-old, a seventh-round pick in 2012, was in the final year of his rookie contract. He has recorded 118 tackles, 13 passes defensed and 21/2 sacks.
"Tough times don't last, tough people do," Allen wrote on Instagram. "I'll be back stronger than ever. All glory to God #JetUp."
Allen played safety and cornerback last season. His career highlights include two blocked punts and an interception for a touchdown.
In a corresponding move, the Jets signed cornerback Keon Lyn. The Syracuse product went undrafted in 2014 and signed with the Indianapolis Colts. He most recently was with the Arena Football League's Jacksonville Sharks.
Notes & quotes: Wide receiver Chris Owusu left practice with an apparent head injury after absorbing a hard hit during team drills. Owusu, who has a history of concussions, felt "woozy," according to Bowles, but the team had no further injury update. The Stanford product had been having a good camp . . . Muhammad Wilkerson (hamstring) did not practice for a fourth straight day.
