FLORHAM PARK, N.J. — The Jets’ banged-up running backs corps just got a boost.

On Monday, the team activated Khiry Robinson off the active/physically unable to perform (PUP) list. His addition on the field couldn’t have come at a better time for the Jets, who still have yet to practice with No. 1 back Matt Forte (hamstring). Veteran pickup Bernard Pierce also has been sidelined with a hamstring injury.

Robinson, who went undrafted in 2013, played in 28 games for the Saints (including three starts) over the past three seasons. He rushed for 766 yards and eight touchdowns on 186 carries. He also caught 25 passes for 178 yards over that span.

His promising 2015 season was cut short in Week 8 against the Giants when he suffered a fractured tibia and was placed on IR.

Robinson had been on the Jets’ PUP list since training camp started.

In other roster news, the Jets signed wide receiver Anthony Kelly and defensive lineman Christo Bilukidi on Monday and waived/injured defensive lineman Julien Obioha.

The Jets also placed wide receiver Chris King on the reserve/did not report list after he failed to show for camp. King was claimed off waivers two days ago after 23-year-old receiver Titus Davis quit football and left camp.
