*Amid heavy rain, power outage at Missouri*

COLUMBIA, Mo.(AP) -- A power outage disabled a scoreboard at the Nebraska-Missouri game and forced officials on the field to use hand signals instead of the play clock.

Columbia had more than 5 inches of rain and flash flooding throughout Thursday. A pregame campus power outage darkened all of Memorial Stadium for about 10 minutes before electricity was partially restored.

A new, $3.5 million scoreboard in the north end zone remained without power by the 8 p.m. kickoff. That meant officials were required to shut off the opposite play clock so one team would not have an advantage.

The game between Big 12 North Division rivals No. 21 Nebraska (3-1) and No. 24 Missouri (4-0) is the conference opener for both teams.
