Tug on Harrison's shoulder helped Mathis on pick

Posted by ESPN.com's Paul Kuharsky

INDIANAPOLIS -- Rashean Mathis bailed out Jack Del Rio.

Del Rio is overly aggressive on fourth downs, and he had his team go for it on a fourth-and-2 from the Indy 11-yard line. Robert Mathis penetrated and tripped up Fred Taylor, who couldn't convert and the Colts got the ball back on downs.

They should have kicked a field goal to close it to 7-6.

But two plays later they took the lead. Peyton Manning's weak pass for Marvin Harrison was easily picked by Mathis, who took it 61 yards for a TD and a 10-7 lead.

CBS' replay just showed that Mathis tugged on Harrison's jersey on his shoulder to help gain position. Tony Dungy saw it live and was in the ear of the officials, to no avail.
