World Rugby is trialing a variation regarding substitutions in sevens. The USA Rugby Committee has approved the use of this Variation in all domestic competitions effective June 18, 2016.
The exact wording is copied below, but in essence it allows a player to return to the game after having been substituted off. The team is still restricted to a total of five substitutions during the game. [This includes any extra time – there are no additional substitutes permitted during additional playing time.]
The Exception that allows a replacement for a player with a blood injury remains, even after a team has made all five of its allowed substitutions.
The Law that allows a temporary replacement for head injury assessment (which is referenced in this Variation) IS NOT APPROVED FOR DOMESTIC USE.
