NEW ORLEANS — An outside expert investigating the cause of a partial power outage during Super Bowl XLVII has confirmed that the failure occurred because a relay device malfunctioned.

Utah-based forensic engineer John Palmer released his findings Thursday.

HOUSTON — Free-agent cornerback Brice McCain has signed a three-year contract to stay with the Houston Texans.

The 5-foot-9 McCain announced on Twitter late Tuesday that he had agreed to terms and thanked his agent, David Canter. The former University of Utah star signed his contract on Wednesday.

Alex Smith didn’t wear a Kansas City Royals baseball cap on the day he was formally introduced as the new Kansas City Chiefs quarterback. He didn’t wear a San Francisco Giants cap, either, or any baseball cap. Instead, he wore a gray suit and white shirt -- and a Chiefs pin in his lapel. Like a grown-up.

“I’m ready for this,” he said. “I’m ready because of what I’ve gone through.”

The formal introduction this week was the first day of Smith’s marriage to the Chiefs, following his quick divorce from the San Francisco 49ers. Both parties sounded infatuated with each other.

CLEVELAND — A person familiar with the agreement says free agent linebacker Paul Kruger, who led the Super Bowl-champion Baltimore Ravens in sacks last season, has agreed to contract terms with the Cleveland Browns.

Kruger, a former Utah Ute, and the club agreed to a five-year deal Tuesday, said the person who spoke to The Associated Press on condition of anonymity because it has not yet been announced by the Browns. Kruger gives the Browns a proven pass-rusher as they transition to a new defensive system.

Albert Haynesworth, leading man.

Albert Haynesworth, villain.

The former NFL defensive tackle earns both roles in an evaluation of free agency over the last five years. He was involved in the best decision made by the Tennessee Titans, and the worst for the Washington Redskins.

A two-time All-Pro, Haynesworth became a free agent in 2009. The Titans bowed out rather than destroy their salary structure, a move that became brilliant when Haynesworth flopped in DC.

KANSAS CITY, Mo. — The new group in charge of the Kansas City Chiefs is going right to work, making bold moves to turn around a franchise that went 2-14 last season.

They traded for a new quarterback in Alex Smith. They locked up two of their own in wide receiver Dwayne Bowe and punter Dustin Colquitt. They franchised left tackle Branden Albert and raised some eyebrows by releasing players once thought to be major free-agent signings.

In doing so, new general manager John Dorsey and coach Andy Reid have put their fingerprints on a franchise that has had one winning season in the last six, hasn’t won a playoff game since 1993, and hasn’t been to the Super Bowl since winning it under Hank Stram in January 1970.
