Arkansas trailed for just 63 seconds in regulation against No.3 Texas Tech but it turned out to be the most important. It also ended up being the minute in a game that brought an entire season crashing down.

Darrion Williams scored the tiebreaking basket with 7.3 seconds left in overtime after tying the game with a 3-pointer in the closing seconds of regulation to lead Texas Tech to an 85-83 win over Arkansas on Thursday night and a spot in the Elite Eight.

The defeat marks the end of John Calipari’s first season as head coach of the Razorbacks, but the team’s deep tournament run provides optimism for the future. Meanwhile, Texas Tech advances to face Florida on Saturday, with a spot in the Final Four on the line.
