LAKE FOREST, Ill. -- With temperatures soaring to 90 degrees outside at the team's training facilities, the Chicago Bears conducted work Wednesday in the Walter Payton Center on a newly installed artificial turf surface.
Bears coach Marc Trestman said there were "a number of reasons" for the change in practice venue.
"I wanted guys to get a chance to see our new surface here," Trestman said. "It's going to be a tool we're going to be able to use during the season at times when we need to get inside. They've practiced very hard in the heat the last two days. It's humid out there today. I thought it would be a good opportunity on a short field on a shorter practice day to just allow them to come inside and see what the organization has done for us to help our football team to get better on the days we need to be inside."
