Garry Lyon has urged Carlton veteran Marc Murphy to fight his way back into the side's midfield after starting the season playing across the half-forward flank.

Murphy, who made his debut for the Blues in 2006, has been a regular in the Carlton midfield for most of his 289 games, but has found himself in a new role for 2021 where he has struggled to get his hands on the ball.

In his All-Australian season, Murphy averaged 29.1 disposals. In the opening five rounds of 2021, he has averaged a career low of 14.8.

Lyon believes that the former No.1 pick should follow the example of Power veteran Travis Boak and re-find his best.

โ€œIโ€™d throw the challenge back to Marc. Heโ€™s on 289 games and at the moment it looks like heโ€™s in that inevitable limping to 300,โ€ Lyon said on SEN Breakfast.

โ€œHeโ€™s playing half-forward and having no impact. Throw the challenge back to him and say get back in the midfield.

โ€œWeโ€™ll give you a couple of weeks to train hard and get some miles back into your legs.

โ€œTravis Boak did it. They took Boak out of the middle and said โ€˜weโ€™re going to make you a high half-forwardโ€™ and after a year Boak said โ€˜no, Iโ€™m going back in the midfieldโ€™ and demanded he went back and trained like a midfielder and is now in the best three midfielders in the competition.

โ€œI think that would send a great message to the rest of Carlton if Marc Murphy stood up in front of the group and said โ€˜I am not satisfied finishing my career as a high forward getting 10 touchesโ€™.

โ€œโ€˜Iโ€™d rather put it all on the line and be what I was for however many years as an elite midfielder and Iโ€™ll go and help Patrick Cripps and Sam Walsh and Iโ€™ll drag Sam Petrevski-Seton with me and whoever else wants to come because Iโ€™m not satisfied withering on the vine on the half-forward flankโ€™.

โ€œYou reckon David Teague wouldnโ€™t look at that and go โ€˜I love this. I love that you are challengingโ€™.

โ€œDavid Mundy is 35 and cruising around like a Rolls Royce in the midfield. I think that might be one of the first steps (for Carlton). โ€˜Liam Stocker you come with me, letโ€™s get this midfield up and goingโ€™ and maybe the other pieces will fall into place.โ€

Carlton have been under increasing pressure after a poor start to the season, with both Patrick Cripps and young gun Sam Walsh offering a spark in the midfield.

The Blues as a team had a disappointing match against the Power on Saturday night and will be hoping to bounce back against the Lions, although it will be a tough asks considering the groove that the Lions find themselves back in.

The Blues sit 2-3 with a challenging month ahead, facing the currently undefeated Western Bulldogs and Melbourne.
