Collingwood's football department has undergone major change behind the scenes this off-season, headlined by the arrival of former Geelong midfielder Scott Selwood as a development coach.

The 29-year-old completes the move having been delisted by the Cats last month, following four years at Kardinia Park often plagued with injuries.

After 169 games, the younger brother of Geelong skipper Joel wasted no time in accepting the role as part of a reshuffle at the Holden Centre, which also saw Matthew Boyd step in as senior defensive coach as a replacement for new Fremantle boss Justin Longmuir.

"Scott has a reputation for being a great clubman and someone who is dedicated to helping develop those around him," Magpies head of football Geoff Walsh told afl.com.au on Tuesday.

"As an academy coach, Scott will be able to focus his energy on helping our emerging talent grow as footballers and as people."

Walsh was also highly complimentary of Boyd's appointment following two years also working as a development coach, as well as Garry Hocking moving from stoppage coach to the top gig for Collingwood's VFL side.

"We're proud to see him develop within our coaching ranks and we expect him to add great value to Nathan's senior coaching group," Walsh said.

"Garry's vast and varied playing and coaching resume makes him a great fit for our VFL program as we have no doubt that the team will be able to learn a lot from him.

"Our coaching panel is finalised and we're confident we have a great mix of experience and skills to work with our players in 2020."
