Clark has been ready.
"He's available," said Coach Dave Wannstedt. "Once we start looking at the game plan, we'll decide who's up and who's down."
The up and down part refers to the 45 in uniform and the inactive list, where Clark has spent the first five games of the season after coming to Miami still nursing a broken forearm.
Wannstedt said the fact the Dolphins are playing Denver will have no bearing on his decision whether to active Clark. Rather, it will come down to how many players they want to dress at each position.
One thing is for sure, when the Dolphins do activate Clark, they'll have themselves another solid pass-catching tight end.
"He's a very good player," said Dolphins senior vice president Rick Spielman. "Like (Olin) Kreutz in the offseason, you don't always have the opportunity to snatch a player like that.
"He's a big-time tight end who can catch the ball. His forte is making big plays."
Clark made plenty of those for the Broncos, catching over 50 passes last season. They released because of his cap number, combined with the fact they were loaded at the tight end position with Shannon Sharpe, Dwayne Carswell and 2002 draft pick Jeb Putzier.
Clark says he holds no grudge toward the Broncos, who drafted him out of Wake Forest and converted him from wide receiver to tight end.
Right now, Clark is more concerned about getting into the action.
"I'm been the biggest cheerleader on the sideline," he said. "When somebody makes a big play, nobody is jumping higher than me or cheering louder. I hope that changes soon so I can go out there and sweat on game day."
Like everybody else, Clark has been impressed with rookie tight end Randy McMichael. And he's ready to do the same things for the Dolphins.
"I bring the same thing Randy brings," he said. "I can make plays downfield.
"I watch him on every play. I envision myself doing the same thing he's doing."
