FLORHAM PARK, N.J. (AP) — The New York Jets have activated tight end Chris Herndon after he completed a four-game suspension and waived linebacker Frankie Luvu.

The Jets had a roster exemption for Herndon that expired Monday, causing them to make a move to clear a spot for him on the active roster. Herndon was banned for the first four games of the regular season for violating the NFL's substance abuse policy.

He was eligible to practice with the team last week, but is sidelined by a hamstring injury. The team is hoping Herndon, who had 39 catches for 502 yards and four touchdowns as a rookie, will return to practice this week.

Luvu was signed last year as an undrafted free agent out of Washington State. He had three sacks and 26 tackles in 18 games the past two seasons for New York.
