Chicago Bears: RB Anthony Thomas should watch his back, and not because he suffered back spasms that kept him off the field Tuesday. In his place, backup RB Adrian Peterson impressed during full-contact drills and showed why coach Dick Jauron has invoked his name so much this offseason. Despite being only 5'10", 210 pounds, Peterson ran up the middle with authority against the No. 1 defense and was difficult to bring down. "I think I can go inside or outside. I'm physical," Peterson told the Chicago Tribune. "I'm not 225 [pounds], or 230, but my heart is big enough." Jacksonville Jaguars: After DT John Henderson became the second Jacksonville player in three days to collapse from the heat, owner Wayne Weaver said the team is considering the construction of an air-conditioned practice "bubble." "We're looking at [a bubble]," Weaver told the Florida Times-Union. "There are a lot of factors on whether that would work or not. We're trying to think it through. [But] We haven't even designed anything yet." Officials said such a structure would cost less than $1 million to build. In the meantime, the team plans to practice at night under portable lights for the first time in their nine-year history.
