The pair will now be unavailable until the back end of the season, with Suns General Manager of Football Operations, Jon Haines, telling the club’s website the pair will soon begin to undergo rehab.
“Both the boys had surgery yesterday on their respective shoulders and both went really well, which is pleasing,” Haines told goldcoastfc.com.au.
“They’ll obviously commence their rehabilitation pretty much straight away.
“Pearce is looking at about a 12 week recovery period and Tommy is looking at a slightly longer one of about 16 weeks.”
Hanley has only played one game for the Suns this season, while Nicholls hasn’t played a senior game of football since round 20, 2016.
Forward Peter Wright is progressing well from a calf injury, and is edging closer to a return to football.
“He’s getting on top of the calf injury, which has been a really frustrating one for him,” Haines said.
“He’s showing some really good signs – he ran really well on the weekend – so he’ll have another solid week of work this week and then we’ll assess him after that.”
