All but Hilliard participated fully in practice on Friday, making it likely that all four will be in the lineup against the Panthers.
Carolina likely won't be as lucky when it comes to quarterback Jake Delhomme.
Delhomme is listed as doubtful on the Panthers' injury report and has not practiced all week, making it nearly impossible to believe that Delhomme will play on Sunday.
That would mean David Carr, the sixth-year pro, would start in his place.
Gruden said he won't take any chances and will continue to prepare for both quarterbacks.
"You have to prepare for the mobility (of Carr)," Gruden said. "You have to prepare for both quarterbacks at this point in time. We all know Jake [Delhomme] is the kind of guy who is tough enough to show up and play his best game of his career. I've been on the wrong end of the stick. He's beat us on the last drive of the game I don't know how many times."
The rest of the injury news is better for the Panthers. Linebacker Adam Seward (calf) is questionable, but participated fully in practice on Friday.
