England hopes boosted by injury to Australia's David Pocock
England's prospects of completing an historic series victory over Australia have soared after David Pocock was ruled out of the remaining two Tests by a fractured eye socket.
Pocock was injured during a collision that occurred as he entered a breakdown and a scan has revealed the extent of the damage with a four to six week recovery time estimated for the number eight.
The development is a massive blow to the Wallabies, who trail 1-0 in the series following their 39-28 defeat in Brisbane and must seek to claw their way back into contention without their most influential player.
Pocock is a master of the breakdown and emerged from last autumn's World Cup as a superstar of the game, finishing with more steals than any other player.
"David played very well in the first Test. We'll have a look at some options that we have," head coach Michael Cheika said.
"We have the option of staying with what we've got or, if we want to bring in almost a like-for-like player, then we'll go with Liam Gill.
"We have options that have got experience, so we're fortunate there, but at the same time it's disappointing to lose a player of David's quality.
"The skills he brings to the game are superb and there's that dynamic that we have in the back-row with himself, Michael Hooper and Scott Fardy."
Pocock, who will remain with the squad, wrote on Twitter: "Gutted to be ruled out of the rest of the #AUSvENG series with a fractured eye socket. Disappointing but these things happen."
