The Pac-12's instant replay system worked properly and its operators did the right thing during Thursday night's controversial basketball finish, the league and the Arizona Wildcats said Friday.

Colorado guard Sabatino Chen made what appeared to be a buzzer-beating game-winner against the Wildcats, only for officials to review and disallow the shot, saying it had not left his hand before the clock expired.

The teams played overtime instead, and the UA won 92-83.

"The system was operating and officials used all the information they had," UA athletic director Greg Byrne said.

Byrne and other Wildcats officials were tight-lipped Friday, referring further comment to the Pac-12, whose director of officiating said Friday the referees were correct.

XOS Digital, which is in its first year as the league-wide high-definition replay provider for basketball, also deferred comment to the Pac-12.

The league then explained how replay works:

• A machine provided by XOS receives three different feeds in real time throughout the game.

Five camera angles come from the television provider - in Thursday's case, ESPNU.

Two more angles come from cameras XOS erected at McKale Center; each camera is located opposite the television cameras, behind the team benches, and shoots toward each basket.

McKale Center's scoreboard also sends a feed to the system.

"I know they used everything that was available," said Pac-12 spokesman David Hirsch, who detailed the system to the Star. "They look at all the video and find whatever's the best.

"They have the ability to stop it frame-by-frame and enlarge it."

• The instant replay technician can access the angles at the instruction of an official. Each school has two technicians, one primary and one back-up, who received preseason training on the system.

• The feeds are sent via a high-definition feed to the courtside computer monitor.

Until this season, teams around the league used either monitors or televisions and could only receive replays by asking television producers or the in-house producers for them.

"It all comes in, and it's being recorded," Hirsch said. "You can look at all the camera angles without asking the producer."

The replay process has remained the same over the years, even if the recording system is new.

Now, as then, officials rule after seeing the best angle they can find.

"This is a judgment call at the end of the game, and a judgment call on the monitor," Hirsch said. "Officials followed proper procedures."
