RUGBY LEAGUE: The Gremlins went down to Tenterfield in an extra-time thriller on Saturday, setting up a knockout semi-final against Killarney this weekend.

Stanthorpe entered the contest on the back of seven consecutive wins, while the Tigers were out for redemption after they lost to the Gremlins in July.

Both sides worked tirelessly in difficult conditions throughout the match, as the game rested on a knife edge.

Tigers captain Brendan Minns missed a penalty goal on the cusp of full-time, which forced the match into 20 minutes of extra time.

But in the early stages of extra-time, Tigers halfback Wesley Doo scored for his side and broke the Gremlins' hearts.

"It was just unreal - by far the toughest game we've played all year," Minns said.

"The Gremlins threw everything at us, we knew they'd be sharp."

The Tigers will now host the 2014 BRL grand final on September 6, when they will take on the winner of this weekend's knockout semi-final between Stanthorpe and Killarney at Sullivan Oval.

Gremlins captain/coach Damian Petrie was proud of his players for their efforts.

"We tackled our hearts out, and they had far more possession than us," he said.

He said his side was determined to bounce back this weekend.

"All the boys have the resolve to now go out and play well on Saturday," he said.

Petrie expected injured duo Ben Staley and Travis Burton to return for the Gremlins on Saturday.

Meanwhile, the Killarney Cutters notched up a hard-fought 16-10 victory over the Texas Terriers in Saturday's other semi-final.

In a further boost for Killarney, key player John Trindall should return to the field against Stanthorpe this weekend having completed his suspension.
