Concussion issue growing - Hazell

Gloucester and former England flanker Andy Hazell tells BBC Points West that the number of concussions in rugby will only increase because of the size and speed of modern-day players.

The 35-year-old, who made 226 appearances over 17 seasons with Gloucester, has been forced to retire after failing to recover from a pre-season concussion injury.
