Henderson to miss Ospreys game following concussion
Ulster captain Iain Henderson will sit out their United Rugby Championship visit from Ospreys on Friday.
The Ireland international suffered a concussion in their win against Connacht last weekend and will now follow World Rugby graduated return protocols.
Centre Stewart Moore sustained a shoulder injury in the same game and will also miss the Ospreys fixture, while fellow backs Jude Postlethwaite and Ethan McIlroy are doubts.
Rob Baloucoune, Jake Flannery, James Hume, Rob Herring and Tom Stewart remain out with longer term injuries, but centre Stuart McCloskey and prop Eric O'Sullivan have returned to training.
