Northwestern fans and Wisconsin fans, get your coffee ready.
You'll be staying up late to watch your teams visit Pac-12 stadiums this season.
The Pac-12 and its television partners announced several start times Wednesday, including three games featuring Big Ten teams.
Northwestern will begin the 2013 season under the lights at Cal's Memorial Stadium. The Aug. 31 game will kick off at 10:30 p.m. ET and be televised by ESPN2.
Two weeks later, Wisconsin will visit Arizona State for another 10:30 p.m. ET kickoff. ESPN or ESPN2 will televise the Badgers and Sun Devils from Tempe, Ariz.
Ohio State also plays at a Pac-12 stadium on Sept. 14, but Buckeyes fans won't have to wait quite as long to see the Scarlet and Gray take on Cal. The Buckeyes-Bears game kicks off at 7 p.m. ET. Fox will televise the game.
Northwestern probably isn't thrilled with the late kickoff, although it's a little easier for teams to get their body clocks right for a season opener. Don't be surprised if the Wildcats head out to the West Coast a little early for the Cal game.
Pat Fitzgerald's team will play four of its first five games at night, as it has three home games in prime time (Syracuse, Western Michigan and Ohio State).
It's no surprise Wisconsin-Arizona State is kicking off at night, and it's a good thing for the Badgers as temperatures in the desert could be brutal for a day game.
Wisconsin will play three road night games in 2013, as it also must visit Ohio State (Sept. 28) and Illinois (Oct. 19) under the lights.
