It was 86 degrees at Saint Thomas Sports Park as the Titans took the field for the first day of their rookie minicamp. Rookie receiver Treylon Burks didn’t make it through.

Burks was laboring in team drills, according to multiple reports, with breathing difficulties before going inside. He later returned, ran a few routes and worked with receivers coach Rob Moore on his releases and head fakes before heading back inside. Burks did not return the second time.
