In the quest to land a Major League Soccer franchise in Detroit, the prospective ownership group has developed one plan that includes installing a retractable roof at Ford Field.

It’s one of several potential scenarios offered by Pistons exec Arn Tellem, who is spearheading the MLS bid along with Cleveland Cavaliers majority owner Dan Gilbert, according to the Detroit News.

Gilbert is studying the cost involved with converting Ford Field. As of now, the home of the Lions is the only acceptable venue for any proposed MLS expansion team in Detroit. Retrofitting the 16-year-old stadium could cost in the hundreds of millions.
