FOXBOROUGH, Mass. — New England Patriots cornerback Christian Gonzalez was again held out of practice on Saturday as he continues to recover from an injury he sustained in a workout last week.

Coach Mike Vrabel didn’t reveal what the injury was that also kept the star cornerback out of uniform for Thursday’s preseason opener against the Indianapolis Colts. But he said Gonzalez is currently conditioning and working to get back to the field.

His absence coincides with his representatives’ ongoing negotiations with the team on a long-term contract extension. The two sides are trying to work out a deal to keep him in New England beyond the final year of his rookie deal. Until last week, he’d remained a full participant on the field, even as workouts shifted to full pads.

Vrabel said everyone involved is on the same page.

“Yes, absolutely. I think that’s the important thing. I’ve talked about his professionalism, everybody else’s. … It was something that happened in practice,” Vrabel said. ”He’s where he’s supposed to be when he needs to be there. Treatment. Working with (director of sports performance) Frank (Piraino) and doing things. That’s my job to be on the same page with everybody here — players, coaches. And I’m confident that’s what they’re doing.”

Patriots offensive lineman Ben Brown is expected to be out for an extended period of time after leaving the preseason matchup with Indy with a leg injury.

Brown started the game at center before leaving in the second quarter.

“Ben’s going to be a few weeks — 4 to 6. Eight, 10, 12 — even numbers. But it will probably be extensive throughout the preseason for sure,” Vrabel said.
