The Pittsburgh Steelers will be without one of their top free agent signings for the early part of the season.

Pittsburgh placed tight end Ladarius Green on the regular season PUP list Tuesday, making him ineligible to join the active roster until after Week 6 of the regular season.

Green, who signed a four-year, $20 million deal with the Steelers this winter, hasn’t practiced all off-season after undergoing ankle surgery.
