Richmond forward Tom Lynch has escaped suspension for his kneeing incident involving Dougal Howard in Friday night's semi-final win over St Kilda.

The incident was Lynch's fifth Match Review case of the season and the star Tiger has been offered a $750 fine by MRO Michael Christian.

Christian did not grade the incident as an impact-contact-intent basis due to how the misconduct findings operate.

Richmond captain Trent Cotchin was not sanctioned for his high tackle on St Kilda midfielder Zak Jones and the incident was not noted in the MRO's announcement.
