PONTIAC, Mich. - Pittsburgh Steelers running back Jerome Bettis says he lost $67,050 worth of jewelry while he was in Michigan for the Super Bowl.

The player known as "The Bus'' said he believes he misplaced a Rolex watch and diamond-studded gold bracelet at the Pontiac Silverdome while practicing for the Feb. 5 game at Ford Field in Detroit. The Steelers beat the Seattle Seahawks, 21-10.

After returning to Pittsburgh, Bettis discovered that he was missing the $31,100 Rolex and $35,950 bracelet, The Detroit News reported Friday. The Steelers stayed and practiced in Pontiac before the game.

"It's being reported as lost property, so it's technically not a crime,'' said Pontiac police Capt. Wendy Keelty-Reyes. "We just got the report ... but we're going to do whatever we can to help recover the stuff for him.''

Bettis, 34, was raised in Detroit.

A lost property report filed Thursday from Pittsburgh said that Bettis believes he removed the jewelry and placed it on the top shelf of his unsecured locker in a pregame practice. He later discovered he was not wearing the pieces and assumed that Steelers personnel had collected and packed them, the newspaper said.

Silverdome security chief John Kissick said he worked during the week of Super Bowl practice and said the NFL also had a security team in place. The practices were closed to the public.

"No one got in or out of there that wasn't supposed to be there,'' he said. "It was tighter in there than Fort Knox.''
