Steelers place TE Ladarius Green on PUP list

PITTSBURGH -- The Steelers placed tight end Ladarius Green on the regular-season physically unable to perform list Tuesday, meaning the team's biggest offseason signing won't see the field until late October at the earliest.

Green is ineligible to practice or join the active roster until after Week 6 of the regular season. After that he has a five-week window to practice. Once he officially practices, the team has 21 days to activate him or place him on injured reserve.

This move isn't surprising, considering Green hasn't practiced all preseason since undergoing ankle surgery, but it amplifies the complications with signing Green to a four-year, $20 million contract in March.

Green underwent the surgery before the signing, and the NFL Network reported earlier this month that Green, who had multiple concussions with the San Diego Chargers, was suffering from recurring headaches. The Steelers have maintained Green was on the preseason PUP list solely for the ankle injury.

Green recently moved forward in his rehab to pool work and jumping, but joining the team never seemed imminent.

The Steelers will start second-year tight end Jesse James, who caught four catches for 25 yards and a touchdown in Friday's preseason game against the New Orleans Saints.
