A Westwood billboard featuring USC quarterback Matt Barkley was covered up Tuesday, but exactly who is responsible remains a mystery.
The board was covered one day after the Los Angeles Times first reported on its placement. Located at Westwood Boulevard and Lindbrook Drive, the billboard shows Barkley, who's looking up, next to the words, "We play to finish," The Times reported.
Athletics spokesmen from both UCLA and USC denied involvement in covering the billboard, according to The Times report, and USC also said the board wasn't meant to taunt rival UCLA team.
Regency Outdoor Advertising, co-owned by a USC donor, owns the board, according to The Times.
