Wellington coach Chris Gibbes has raised questions over Otago's use of substitutions in Wellington's 27-24 Mitre 10 Cup victory today.
Otago had three players - Josh Ioane, Jonathan Ruru and Mikaele Mafi - leave the field only to return later in the game.
The trio spent between 10-15 minutes off the park, and while Mafi returned for a different injured player, both Ioane and Ruru were called back into action for their direct replacements - Hayden Parker and Josh Renton.
Gibbes raised the issue as part of a competition-wide trend, arguing that the moves could be seen as giving players rest via rolling substitutions.
"There's a tactical, and there's an injury replacement when you make a substitution - one can come back on the field and the other one can't. So effectively you've got rolling subs."
