The SEC issued a statement Friday that Vanderbilt can no longer wear its "Anchor Down" jerseys used in place of the players' last names.

Vanderbilt's jerseys were the subject of controversy during the Commodores' season-opening 37-7 loss to visiting Temple on Thursday night.

The SEC called the NCAA's approval of jerseys that "are not permissible under the NCAA football uniform regulations" a "miscommunication."

The NCAA has ruled previously that all schools except the military service academies may not put slogans on the back of their players' jerseys.

The controversy on Thursday night began at the start of the second quarter when the officiating crew announced that the Commodores were being penalized one timeout for wearing the "Anchor Down" jerseys and would continue to be charged an additional timeout per quarter for the duration of the game.

Vanderbilt officials then showed referee Ken Williamson an email printout, which apparently indicated that the Commodores had sought and received permission to wear the jerseys. Williamson then restored the lost timeout and announced that there were no further problems with the jerseys.

"I don't know if it's wrong or not," Vanderbilt athletic director David Williams told The Tennesseean, "but they had approved it."

Chuck Dunlap, communications director for the SEC, issued a statement from the conference:

"A miscommunication resulted in Vanderbilt wearing jerseys during its football game Thursday night that are not permissible under the NCAA football uniform regulations. Before production of the jerseys, Vanderbilt sought approval of the jersey design from the NCAA, which included the words 'Anchor Down' on the back panel. The NCAA responded with written approval of the design as presented and Vanderbilt proceeded with the jersey production, assuming the approval was applicable to the slogan as well as the colors and overall design in the submitted layout.

"NCAA football regulations do not permit the use of slogans on jerseys. Vanderbilt was originally penalized for the jerseys during the game and after being shown the written correspondence, the head referee also interpreted the correspondence to mean the slogan had been approved. Vanderbilt has been notified it cannot wear the slogan on its jersey for future games and has agreed to comply."
