Ireland rugby captain Johnny Sexton has responded to comments from two French doctors who said he shouldn't play against France this weekend after sustaining a head injury against Wales last Sunday.

Speaking in a press conference, Sexton said he was disappointed by "inaccurate" claims that he had sustained 30 concussions throughout his career.

Is it appropriate for Sexton to play so soon after a head injury, and how serious a problem are such injuries in rugby?

David Kelly, Chief Sports Analysis Writer with the Irish Independent, and former Ireland international Paul Wallace joined us to discuss this.
