PEARCE and Cian Hanley will return home to Ireland immediately to deal with an urgent family matter.
In a joint statement, the Gold Coast Suns and Brisbane Lions said they would "provide all the support the family needs during this challenging time."
"Both clubs ask that the media respect the privacy of the players and the Hanley family at this time."
The pair were together at the Brisbane Lions in recent years before Pearce was traded to the Suns in this past trade period.
The brothers spent extra time during the Christmas and New Years period in Ireland with their terminally ill younger brother Tom.
Tom's battle with stage four cancer was put in the spotlight when WWE and film star Dwayne 'The Rock' Johnson sent out a video message supporting him.

"This one's for my buddy Tommy Hanley. Just found out he's a huge fan, 15yrs old, living in Ireland and battling stage 4 cancer,'' Johnson said on Instagram.
"I've never met you, but I already know so much about you and can tell you're an awesome, honourable and strong young man.
"Make sure you eat up dude and get your rest. Those two things are gonna help you stay strong during this fight.
"Stay being the coolest kid and always keep in mind how much you inspire all your family and friends - including me.
"We're all pulling for you Tommy! Stay strong and Merry Christmas to you and your family - Uncle Rock aka Dwanta Claus.''
