Cats star Paul Chapman will not line up against Richmond after withdrawing with hamstring tightness.

Chapman reported the issue after training on Friday morning. He missed last week’s win over the Bulldogs with the same issue.

Jordan Murdoch has come into the team as a replacement with Josh Caddy added to the emergency list.

Murdoch played in the opening round win over Hawthorn and the round three victory over Carlton. He has played 10 games since debuting midway through the 2012 season.
