Kevin Sumlin did not meet with the media today for his typical Monday press conference since it is a bye week. He did, however, have his first weekly radio show appearance tonight and he confirmed that starting cornerback Lorenzo Burns has a concussion after taking a big hit in the game against Hawaii. The extra week should give him some time to get right after the concussion, but Sumlin also had positive things to say about freshman Bobby Wolfe who had to come in and help fill Burns' spot.
