It sounds almost funny now, but there was nothing funny about what Koskie was going through after he suffered a concussion during a Major League baseball game. “Headache, nausea, dizziness — you just kind of go down the chain. I had it all,” said Koskie. Koskie was playing third base for the Milwaukee Brewers when he chased a little flare. He dove and landed awkwardly. “I just look at the film today … and I think, how could I have gotten hurt from that one?” But hurt he was — so much so that it ended his career. Friday Koskie spoke to a group of more than 700 athletic trainers at the Hilton in Minneapolis for their national symposium. He told them about the injury, and the three plus years it took for him to recover.
