List Manager Jason McCartney said Murphy’s intention to play on was welcome news.

“It goes without saying that Bob is such a key figure at our football club,” McCartney said.

“His on-field performances have continued on at the highest of levels, and his leadership has been first rate.

“We are proud to call him a Bulldogs player, and are excited about the prospects of our team under his leadership.”

The 2011 All-Australian, who was announced as Captain at the end of last year, has played 278 games for the Club since being drafted with pick 13 in the 1999 National AFL Draft.
