Ten other players participated in practice on a limited basis. The Patriots will taper off their activity at today's session.
"Obviously, we don't have much new going in, just kind of making sure everything we have going in we've got right," Belichick said.
The Patriots plan to hold a walk through on Saturday.
On Wednesday, Belichick took a half-hour break in practice to simulate the extended halftime for the Super Bowl.
"It's not perfect but it's the best we could do," Belichick said. "Practice, take a break, come back out and re-start."
