Former Wales international Alix Popham has slammed the decision to allow Tomas Francis and Owen Watkin to continue playing at Twickenham on Saturday.
In the first half of Wales' defeat to England, Francis and Watkin were both involved in a heavy collision that left them appearing to be struggling for balance on the field.
Blood poured from a cut on Watkin's head as he struggled to get to his feet, while Francis was seen leaning against a post for support.
