Rugby concussion: George North decision surprises Mike Tindall

Former England captain Mike Tindall says it is "strange" Wales winger George North was not taken off for concussion during their 21-16 Six Nations defeat on Friday.

It comes as the number of reported concussions in English rugby rose by 59% in 2013-14 compared with the previous season - according to the latest annual injury audit.

Wales head coach Warren Gatland last week defended his medical staff after the sport's governing body World Rugby asked the Welsh Rugby Union to explain why North was allowed to continue.
