The Carlton coaching position has been narrowed down to four men, as the Blues close in on a new senior coach.

Carlton is believed to have narrowed the list of coaching candidates down to John Barker, Brendon Bolton, Stuart Dew and Simon Lloyd.

However, the most fancied candidate is understood to be current Hawthorn assistant coach Brendon Bolton.

Bolton is seen as a big chance to be appointed coach given the success he has had at the Hawks in recent years.

The 36-year-old took the Box Hill Hawks to the VFL finals in 2009 and 2010 and has since become a senior assistant under coach Alastair Clarkson. He also took the reins last year when Clarkson took time away from the game due to illness, winning all five games he coached.

Bolton also won a premiership as a captain-coach with Hobart when he was just 24.

The Herald Sun has reported that an appointment could be made within the next two weeks.
