FLORHAM PARK, N.J. (AP) The New York Jets activated running back Khiry Robinson from the active/physically-unable-to-perform list Monday after he sat out the start of training camp while rehabilitating from a broken right leg.

Robinson was limited to position drills, but it marked the first time he was on the field participating in any portion of practice since he was signed by the Jets in March as a free agent. He briefly worked in the rehab area after going through running back drills, then watched the rest of practice from the sideline.

''He was only scheduled to do individuals,'' coach Todd Bowles said, referring to the trainers' plans.

Robinson joins a Jets banged-up backfield that includes just three healthy players: Bilal Powell, Romar Morris and Dominique Williams. Both Matt Forte and Bernard Pierce are both dealing with hamstring injuries and are unlikely to play in the preseason opener Thursday against Jacksonville.

Bowles said it was too early to rule out Robinson for Thursday's game.

''We're going to take a look at him tomorrow and see how he's feeling, if he has any after-day soreness and we'll make a game-time decision.''

Robinson spent his first three NFL seasons with the New Orleans Saints. He broke his right tibia during a game against the Giants in November and was placed on season-ending injured reserve after needing surgery.

Robinson was signed by the Saints as an undrafted free agent out of West Texas A&M in 2013. He's played in 28 games in three NFL seasons, rushing for 766 yards and eight touchdowns and catching 25 passes for 178 yards. He appeared to be on his way to the best season of his career before the injury, rushing for 180 yards and four TDs while catching a personal-best 17 passes for 115 yards.

The move was one of several the Jets announced Monday. They also waived/injured defensive lineman Julien Obioha and placed wide receiver Chris King on the reserve/did-not-report list after claiming him off waivers from Atlanta on Saturday.

New York also signed wide receiver Anthony Kelly and defensive lineman Christo Bilukidi.

Kelly had been with Tampa Bay this spring after being signed as an undrafted free agent out of Kutztown University. The Angolan-born Bilukidi was a sixth-round draft pick for Oakland out of Georgia State in 2012 and has one career NFL sack. He has also spent time with Cincinnati, Baltimore and Washington, which released him in May.

NOTES: After their on-field tiff during practice Friday, CB Darrelle Revis and WR Brandon Marshall had no issues during team drills. ... DE Muhammad Wilkerson (leg), RT Breno Giacomini (back) and WR Devin Smith (knee) all remain on active/PUP and likely won't play against the Jaguars. ... WR Eric Decker sat out with what Bowles said was sore legs. He's expected to return to practice Tuesday. ... Bowles was uncertain as to whether all four quarterbacks on the roster - Ryan Fitzpatrick, Geno Smith, Bryce Petty and Christian Hackenberg - would play in the preseason opener. The coach said he would discuss that with offensive coordinator Chan Gailey and quarterbacks coach Kevin Patullo. ... Bowles indicated that veteran Jeremy Ross and undrafted rookie Jalin Marshall from Ohio State will get the first cracks at returning punts.
