When the NFL kicks off its season in September, a few female athletic trainers will be on the sidelines.
But for many years, there was just one, and she was from the University of Wisconsin.
Sonia Gysland, hired by the Pittsburgh Steelers in 2011, made sure her gender was not nearly as important to her as how she did her job.
"It's very rewarding work because you're helping these people make a living," said Gysland.
Her duties are wide ranging, from treating injuries on the sideline to unloading equipment at the stadium on the road to taping ankles for the superstitious players who will only go to the same trainer every time.
