Veteran wide receiver Dane Looker, who has been on a medical roller-coaster for a couple of weeks, finally got a diagnosis for the abnormality that was discovered in his brain. Looker has a rare condition — only 150 cases known worldwide, according to his doctor — called a dolichoectatic artery in his brain.

Basically, it’s an artery that is slightly larger and longer than normal. It doesn’t affect Looker’s football career, although he’ll have to undergo regular MRI exams for the rest of his life to make sure that the condition isn’t worsening.

“It’s just a random thing,” Looker explained. “The chances of anything negative happening to me for the rest of my life are very slim.”
