Steven Motlop is now a member of Port Adelaide after Geelong decided not to match the Power's offer to the restricted free agent.
The 26-year-old spent the past eight seasons with the Cats, and has played 135 games for Geelong since making his debut in round two, 2010.
“It was a difficult decision to leave Geelong,” Motlop told portadelaidefc.com.au.
“I spent nine great years there and they were fantastic for my footy and a great support for me and my family.
“Having decided to leave, I was really impressed by the presentation Ken Hinkley and some of the club’s other leaders made.
“I already have a connection to the Power where my older brother, Daniel, played for six seasons and my cousin, Marlon, still works in the community department.
“Port Adelaide is also an industry leader with its Indigenous community work, which is an area that is really important to me.”
Port Adelaide List Manager Jason Cripps said the club was thrilled Motlop decided to join the Power, and is excited to see Motlop in action next season.
“It’s a great vote of confidence in our football program, and club more generally, that Steven has chosen to join us,” Cripps said.
“He’s a highly skilled and experienced player who we believe will make an immediate impression with our side.”
