I suffer from Cluster headaches. Last thing I want to do is miss this game. Appreciate the support from fans. Rooting for my bros! #HTTR

Knighton missed practice Monday because of the headaches and spoke at length about them during the week. Once the headaches begin, the bouts re-occur for days or even months. Knighton said Thursday he's never missed a game because of the headaches.

The pain, according to doctors, can be worse than a migraine, but a single episode does not last as long. Knighton said he's been to at least 30 doctors over the years, and though some say certain treatments can help, nothing has worked for Knighton, who also said he has received injections for the pain to no avail.
