Mike Tomlin: He Gone!

The official announcement will come either later Saturday or on Sunday.

Tomlin, 34, impressed the Steelers during the interview process with his organization skills, intelligence and grasp of the game, according to a source familiar with the coaching search.

A report on Sports Illustrated's Web site, SI.com, on Saturday indicated that Tomlin had been chosen as the successor to Cowher, but the Vikings' defensive coordinator told ESPN's Chris Mortensen that no decision had been made.

"It is untrue," Tomlin said of the report. "I have no idea where it's coming from. I have not talked to the Rooneys today."

Sources also told ESPN.com's John Clayton that the report was incorrect, and the Steelers are not expected to make a decision Saturday.

The team also did not confirm the report Saturday.

"We have heard all the rumors, and we have nothing to confirm at this point," Steelers spokesman Dave Lockett said, according to the Pittsburgh Post-Gazette.
