For the third game in a row, Steelers Coach Mike Tomlin declined to reveal his quarterback rotation for Saturday night's third preseason game in Denver.

However, he did say each of his three top quarterbacks would play against the Broncos, meaning Ben Roethlisberger is likely to start.

Tomlin did confirm that Dennis Dixon will play with the first team, an opportunity he has earned "based on merit."

"Dennis Dixon has done a great job," Tomlin said. "We thought he was deserving of some first-team snaps with our people."

Tomlin said rookie No. 1 draft pick Maurkice Pouncey would start at center and indicated he would not rotate him with Justin Hartwig with the first-team offense. The Steelers had done that each of the first two games when Hartwig started.

Also, Tomlin said new long-snapper Matt Stewart will handle all the snapping against the Broncos, a sign that Greg Warren's job might be in jeopardy. Stewart was released before training camp when the Steelers signed Flozell Adams, but was re-signed last week.

"We wanted to get him back here to give him the opportunity we intended," Tomlin said.

CB Bryant McFadden will not play (pectoral muscle) and will be replaced by Keenan Lewis. Veteran Will Allen will start at free safety for Ryan Clark, who will be held out for preventive health reasons.
