Murray landed heavily on his shoulder in the dying stages of the match and the extent of the injury has ended his season with a suspected broken collarbone.

The Lions' victory has qualified them for the preliminary final this Saturday, while for the Goannas its fourth straight loss has ended its season.

On a positive outlook, it appears Lions' midfielder Riley Corbett will return from injury for this week's clash against Leeton after missing the past month.

GGGM set up the victory with a brilliant first quarter when they booted four goals to nothing, with Jacob Olson and Matt Neagle dominating.

It was a late goal by Neagle in the third quarter that extended the lead to 39 points going into the final quarter.

MCU Eastlakes was its own worst enemy at times, with poor conversion in front of goal after having the same scoring shots as the Lions.

Wagga Tigers has held off Leeton Whitton to advance to the Riverina Championship grand final on September 19 at Robertson Oval.

In one of the best games of the season, Wagga fought back from almost four goals down in the second quarter to win by three points.

Leeton Whitton was left to rue a poor third term when they failed to score after booting eight goals in the first half.

The Tigers' defence completely shut down the Crows' forward strategy. Wagga's two goals for the quarter was enough for them to take a lead into the final term.

Wagga started the final term best and extended the lead to over three goals before the Crows charged home with two late goals.

Lahn Shepherd, Brendan Myers, Charlie Bance and Luke Gestier were excellent for the Tigers along with Shaun Driscoll and Shaun Flanigan.

Leeton Whitton's two key forwards, Jade Hodge and Cooper Sharman, were both well contained with just two goals each. Lucas Meline was best for the Crows.

In a surprise result in the thirds, Leeton Whitton inflicted a four-point loss on minor premiers, Osborne, in a highly entertaining contest.
