From the Arizona Republic’s Laura Houston.

The Arizona Cardinals have apologized for a sound-system glitch that marred Sunday’s tribute to Pat Tillman and will replay a video honoring him at Sunday’s game against the Detroit Lions two hours before the 2:05 p.m. kickoff.

Fans stood during halftime of the Cowboys game on Sunday at University of Phoenix Stadium as Tillman’s name was added to the team’s Ring of Honor at the Glendale stadium.

A video montage on the stadium’s giant screens was to paint a touching portrait of the man who exchanged life as a professional athlete for that of an Army Ranger. Former teammates talked about Tillman’s spirit and his legacy after dying in Afghanistan in a friendly-fire attack in April 2004.

The fans did not hear a word until the last segment.

The sound glitch silenced the tributes, and fans were angered at the perceived disrespect shown to a football player many of them had followed for years at Arizona State University and with the Cardinals.
