I just read at Bucknuts that Urban Meyer had a headache that caused him to take a knee briefly during the Indiana game. Somehow, the report was linked to a surgery he had in 2014 to remove a cyst. According to what I read, he has struggled with these headaches all year. Is there more information, or is that pretty much it?

FTR, I did several searches here on health, Meyer's health, headache, cyst, but came up with nothing. If this has been written about and I just missed it, please let me know. Thanks!
