Waratahs hooker Tolu Latu was relegated back to club rugby after missing a Waratahs training session last week, crossing for Sydney Uni in a thrilling draw against Manly.

Scrumhalf Mitch Short, who spent time with the Western Force as injury cover earlier this year, was another to impress for the Galloping Greens.
