O'Driscoll: It's not over

Brian O'Driscoll could not contain his disappointment after the British and Irish Lions slipped to an agonising 16-15 defeat in the second Test against Australia but warned the Wallabies: "It's not over."

The Lions were on course for a first series triumph since 1997 as they led for most of the match in Melbourne and had a chance to snatch the win with a 50-metre penalty with the last act of the game.

However, like Australia's Kurtley Beale did last weekend as the Lions snatched a dramatic 23-21 win in Brisbane, Leigh Halfpenny could not convert and the home side were able to celebrate a series-tying victory to set up a grandstand finale in Sydney next Saturday.

O'Driscoll admitted the Lions were a "bit loose", saying on Sky Sports 1: "Obviously we're very disappointed. We were ahead in the leaderboard, we got six points clear, that's a horrible margin, a converted try and you're behind.

"They battled away and, we were a bit loose with aspects of our game and gave them opportunities to build the platform to get their score."

However, the veteran centre also insisted: "It's very disappointing but it's not over.

"We've got one massive week next week, both from a mental point of view and a physical point of view to get ourselves right for Saturday in Sydney.

"We knew it was never going to come easy and they made it tough on us."

Of next weekend's decider, the Irishman added: "It's huge, the momentum from this game is with them but we won't let that phase us, we'll dig deep.

"We were able to beat them once and there's no reason why we shouldn't be able to do it again if we can get our game right."
