Pittsburgh Steelers tight end Ladarius Green has not been able to practice with the team this preseason, and has been held out due to recurring headaches rather than complications with his surgically-repaired ankle, Aditi Kinkhabwala of NFL.com reports.
The Steelers signed Green as a free agent this off-season, agreeing on a four-year, $20 million contract in March. His ankle injury kept him out of spring practices and he remains on the physically unable to perform list.
Steelers head coach Mike Tomlin has not directly addressed the situation. Although the cause of the headaches is unknown, Green did sustain two concussions in the span of 11 days last season, which were his second and third in less than a year.
Green was selected in the fourth round of the 2012 NFL draft by the San Diego Chargers. He spent four seasons with San Diego before joining the Steelers. Over the course of his career, Green has recorded 1,087 yards for seven touchdowns.
