Brock Rosenkranz’s first concussion came on the football field during his freshman year at Richland Center High School. The otherwise sturdy offensive lineman, who packs 255 pounds on his 6-foot-6 frame, kept the injury to himself so he could finish the season.
He didn’t realize he would never play football again.
A few months later, while playing varsity basketball, Rosenkranz sustained three more concussions over a span of two and a half weeks. He sat out for nearly a month, returning to suffer yet another concussion while rebounding late in the regular season.
He gave up football as a sophomore but stayed with basketball, which led to three more concussions. Left with headaches, memory loss and withdrawn behavior, he finally took his doctor’s advice and gave up contact sports.
