Way back in 1961 or so I was at practice for my little league team. The coach was hitting fly balls for us to shag. He hit a dribbler that I ran in to pick up and throw back to him. When I was half way back to the pack there was the crack of ball against bat. I turned around, only to take a line drive to my forehead. The next thing I recall was coming to with the coaches and the the entire team standing over me, my glove under my head.
After I seemed to be all right, I was doing some infield practice. When I turned pale as a ghost (I lived in St. Pete Beach, FL at the time so was tan all year round) and puked my guts out, the coach decided I should go home. A half mile. No biggie to walk. Except that I had a concussion. And there was no one around when I got home.
It took me weeks to "get back into the game."
My point? I'm sorry to hear about what's happened to Wenger. I hope all goes well for him. I'm also glad to know that in today's atmosphere there is now a greater concern for the effects of concussions. Not to mention care and caution.
I hope that he suffers no serious, lasting effects. I applaud the care and concern for his future 40 years from now, not just 4 days.
