SECOND-year player Daniel Markworth will undergo knee surgery this week after injuring his ACL during a skills session at pre-season training.

In his first season on St Kilda’s list, Markworth played 14 games for Sandringham’s senior VFL team and kicked 10 goals. His best performance of the year came in the elimination final loss to Box Hill, where he had 23 touches and kicked three goals.

Markworth was named as an emergency for several games in the second half of 2012.

A timeline around Markworth’s recovery will be determined following surgery.
