CHICAGO -- Three days before hosting their biggest game at Soldier Field in years, the Chicago Bears are exploring moving outside the city for which they are named.

In an open letter to fans Wednesday evening, team president and CEO Kevin Warren said the Bears will explore other locations -- including outside of Cook County, where the team owns a 326-acre property in Arlington Heights, Illinois -- to build a domed stadium.

That includes moving the Bears out of Illinois altogether.

"In addition to Arlington Park, we need to expand our search and critically evaluate opportunities throughout the wider Chicagoland region, including Northwest Indiana," Warren said. "This is not about leverage. We spent years trying to build a new home in Cook County. We invested significant time and resources evaluating multiple sites and rationally decided on Arlington Heights.

The Miami Dolphins are benching quarterback Tua Tagovailoa and turning to rookie Quinn Ewers as their new starter, coach Mike McDaniel said Wednesday.

Ewers' first start will come Sunday against the Cincinnati Bengals. Ewers served as the team's backup quarterback for its Week 7 loss to the Cleveland Browns and briefly entered the game but has otherwise been the Dolphins' emergency quarterback.

"Quinn gives us the best chance to win," McDaniel said.

Quarterback Zach Wilson, the 2021 second overall pick by the New York Jets in the 2021 draft, will be the backup Sunday, while Tagovailoa will be the emergency third quarterback.
