Apparently Luke Bryan was cheering too hard for his favourite college football team on Monday, and as a result, he has to stay quiet for awhile. He is on vocal rest until his Crash My Playa next week. Technically, Luke is supposed to perform during two of the four nights, but he's usually around each day of the event. His Las Vegas residency is scheduled to start a few weeks after Crash My Playa wraps up. That residency continues until February 26th.
