Apparently, New England Sports Network viewers who were watching Boston College's upset of North Carolina on Sunday were switched to the Duke-Virginia Tech basketball game with less than a minute left in the UNC-BC game. Here's a brief report about the mixup from the Boston Globe:

With 1:26 to play, NESN lost its feed of the game. The feed came from Fox Sports, and Fox mistakenly switched NESN to the Duke-Virginia Tech game (commercials were shown locally). The correct feed returned with about five seconds to play. NESN public relations manager Gary Roy apologized and said the network was looking into the problem.

FOX Sports South produces the "ACC Sunday Night Hoops" games, but they are distributed by FOX in Los Angeles through the network's master control facility in Houston. FOX is trying to determine what caused the problem.
