Rob Gronkowski returned to practice on Saturday but remains in the concussion protocol. 

Participating in football-specific drills is the fourth step, followed by full football activity.

"It's always great to have him out there," quarterback Tom Brady said Saturday. "He's a great player, great person, great teammate and a big part of what we do. So it obviously hurts when he's not out there for a lot of reasons, but he's doing the best he can do, and we're all hopeful."

The Eagles are expecting Gronkowski to play in the Super Bowl.
