Warren Gatland has selected Alex Corbisiero in his British and Irish Lions team for Saturday's first Test against Australia in Brisbane.
The 24-year-old England man, who joined the squad following injuries to Cian Healy and Gethin Jenkins, will partner Tom Youngs and Adam Jones in the front row.
George North's return means that he is included in the side, although Jamie Roberts, Manu Tuilagi and Tommy Bowe all miss out through injury.
"After six matches we have arrived at the first Test and have selected our strongest possible side with only Jamie Roberts, Tommy Bowe and Manu Tuilagi unavailable for selection," said Gatland.
"The Wallabies at home pose a huge challenge but the Test team contains 20 of the players that played against the Waratahs in what was our best match to date. We now have a couple of more days of match preparation to ensure we improve again on that performance."
The Lions lost to the Brumbies on Tuesday.
Team in full:
15. Halfpenny, 14. Cuthbert, 13. O'Driscoll, 12. Davies, 11. North, 10. Sexton, 9. Phillips, 8. Heaslip, 7. Warburton, 6. Croft, 5. O'Connell, 4. A-W Jones, 3. A. Jones, 2. Youngs, 1. Corbisiero
