LONDON coach Joey Grima was overjoyed after seeing the Broncos finally claim their first victory of the Super League season with a stunning 40-36 comeback win over Leeds Rhinos.

The Londoners looked dead and buried when they trailed 30-8 with 45 minutes on the clock, only for a Joe Keyes-inspired revival to earn an unlikely two points – and end a run of 23 league defeats.

Keyes ran in a hat-trick of tries, including two in the closing ten minutes, as an under-strength Leeds side suffered a setback ahead of their Challenge Cup final date with Castleford next weekend, missing the chance to claim second spot in the process.

Grima said: "I know Leeds had players missing but they still had a quality team out there and to come back like that is hard to believe.

"Given the season we have had, to produce a performance like that takes some doing. If I'm totally honest, I am pretty emotional about it all.

"There's a great atmosphere in the dressing room, although most of the players don't actually know the words to any victory songs."

Leeds rested a host of players ahead of the contest, with only four remaining from last weekend's semi-final defeat of Warrington.

In a see-saw game, Kallum Watkins, Josh Walters and Liam Sutcliffe ran in tries to open up a 14-0 Rhinos lead early on.

After Jordan Atkins and Keyes responded, Leeds kicked back into gear and tries from Mitch Achurch, Zak Hardaker and Sutcliffe appeared to have put the game to bed.

But the Broncos had other ideas as tries from Kieran Dixon, Mike McMeeken, Scott Moore and Keyes made it a one-score game with ten minutes left.

The comeback was completed when Keyes struck for his third try, having danced away from a host of Leeds tacklers on his way to the line.

Leeds coach Brian McDermott said: "I know people think we do not care about the league because of the Challenge Cup but that is absolutely not true.

"In fact, if we miss out on top spot because of this game I will be very disappointed.

"There were individual errors out there that are totally unacceptable. We did not play badly as a team but there were too many mistakes from players.

"Credit to London though, they did not go away and that says a lot after the long, hard season they have had."

Meanwhile, Huddersfield maintained their late-season momentum with a fourth straight win to leave Widnes sweating over their play-off spot.

While a 28-14 victory, masterminded by reigning Man of Steel Danny Brough, kept alive the Giants' hopes of a top-four finish, the Vikings are just two points ahead of Hull KR in their battle to hang on to eighth place and secure a first-ever play-off spot.
