Close scores, extra time and spring weather combined to make last weekend's Group 20 finals an enjoyable day out for fans, but spectator behaviour kept officials busy.

At the end of the Hay Magpies and Leeton Greens first grade semi final at Yanco Sportsground, a minor scuffle broke out at the end of the high-pressure game.

It escalated when an spectator also entered the field.

Earlier in the match, tensions had spilled over and a trainer allegedly became involved in the fracas.

On Sunday, a spectator was warned by the ground manager, after being accused of abusing a line official.

The spectator was ultimately ordered from the ground.

Both Group 20 and NSW Rugby League have been contacted for comment.
