The Facts: The Steelers made just one splashy -- and much-needed -- free agent signing this past offseason, 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.

Diehards Line: Green signed a four-year, $20-million contract in March, which included a $4.75 million signing bonus, but he has yet to practice one play. His ankle surgery in January ostensibly kept him out of spring practices and minicamp and he's spent the entirety of training camp on the PUP (physically unable to perform) list. HC Mike Tomlin has maintained that Green's sustained absence from the field is not entirely unexpected, and he reiterated that Wednesday, as he readied his team for its preseason opener Friday against the Lions. Remember: Green, then a member of the Chargers, complained of headaches after suffering two concussions in two weeks last September. 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 and Profootballtalk.com's Mike Florio reports that sources tell him retirement is an option if the headaches persist. ... Stay tuned. This bears watching.
