"Adam is five weeks post injury now, and the problem has settled down well. We are starting to increase his functionality during rehab this week, after which we will be in a position to target a game for his return to action"
Meanwhile, centre Andrew Bishop has completed his recovery from ankle ligament damage suffered in the New Year's Eve Welsh derby against Cardiff Blues at the Cardiff City Stadium. Towers confirmed:
"Andrew has done really well in his rehab and has returned to full training this week, meaning he is available for selection for Sunday's game against Connacht."
