Despite passing a concussion test earlier in the week along with Montell Owens and Kevin Rutland, Jaguars wide receiver Laurent Robinson has yet to make his return to the practice field as he watched from the sideline for a second consecutive day.

"The concussion players all passed the concussion tests and are cleared by the doctors," Jaguars head coach Mike Mularkey told reporters on Wednesday. "We're going to be smart with those guys and limit contact with them, just today, just to make sure that they stay that way, they stay cleared."

Apparently such is not the case for Robinson though, as his contact was evidently limited for more than one day and has now cast his availability for Sunday's game against the Bengals in doubt.

If Robinson were unable to start, the replacement starter would likely be between Cecil Shorts III and Kevin Elliott. Upon leaving the game in the first quarter, it was Elliott that received Robinson's snaps in his place. However, given Shorts's production, he may get more of an opportunity moving forward.

Post-practice, Mularkey told @vitostellino that Robinson did have a setback but hopes he can be full practice Friday.
