AFL legend James Hird has come out swinging against speculation that Adelaide Crows coach Matthew Nicks could be shown the door if his side is eliminated this Saturday night, labelling the suggestion "absolutely ridiculous."

Hird made his feelings clear on the heat being directed at Nicks in the lead-up to the high-stakes elimination final, pushing back firmly on the notion that a single-game exit should be enough to put the coach's position in jeopardy.

The criticism from the former AFL star adds a notable voice to what has become a growing debate around Nicks' future at the Crows, with the club's season set to hinge on the outcome of Saturday evening's do-or-die clash.
