Sean Cavanagh fears long-term concussion effects after 'scary' injury

"I was sitting in work a few weeks later. I still was feeling nausea. I was still feeling sick. My balance wasn't right. My sleeping wasn't right."

Sean Cavanagh has said he suffered nausea and issues with his balance and sleeping for weeks after a concussion he suffered in September.

He sustained the concussion, a broken nose and facial injuries while playing for his club, Moy, in the Tyrone Senior Football Championship.
