Source: Headaches, not his ankle, keeping Steelers TE Ladarius Green on the sideline

The Steelers made just one splashy -- and much-needed -- free agent signing this past offseason, tight end Ladarius Green. They have yet to see him in their offense, though, and a member of the organization, informed of the player's health, said it has nothing to do with the tight end's surgically-repaired ankle -- but is instead an issue with recurring headaches.

Green's agent, Adisi Bakara, however, immediately said, "His ankle is fine," when reached Wednesday night. Bakara would not comment on what is ultimately keeping Green sidelined, and his client has reportedly been seen running sprints at St. Vincent's College, while his teammates practice.

Green, then a member of the Chargers, complained of headaches after suffering two concussions in two weeks last September, according to a report in the San Diego Union-Tribune. Those were his second and third concussions in less than one calendar year. Green sat out one game last season due to a concussion, while ankle issues sidelined him for two others. A concussion also caused Green to miss one game during the 2014 season.

Green landed in a great situation, but it sounds like he continues to have symptoms from previous concussions. There's no telling how this is going to play out, so we're moving Green down our draft board until he's able to return to practice. In redraft formats, given his upside, Green is a good late-round pick as a TE2 but for now he can't be counted on as a fantasy starter.
