FOXBORO, Mass. — Add another injury to the New England Patriots’ growing list of ailments.

Patriots safety and special teams ace Nate Ebner was spotted Thursday with a hard cast on his right arm as he walked onto the practice field for the team’s walk-through. Ebner wasn’t spotted with the cast prior to Wednesday’s walk-through.

Most of the Patriots dealing with injuries, including quarterback Tom Brady, wide receiver Julian Edelman, linebackers Dont’a Hightower and Jonathan Freeny and defensive end Chandler Jones were present for the session. Defensive tackle Sealver Siliga, who missed the Patriots’ Week 17 loss to the Miami Dolphins for non-injury related reasons, hasn’t been spotted the last two days.
