Marcus Smith will make his British and Irish Lions debut against the Stormers in Cape Town on Saturday.
Smith, who won his first England cap against the USA two weeks ago, only joined up with Warren Gatland's squad on Monday after Finn Russell sustained a potentially tour-ending torn Achilles.
The Lions are experiencing an injury crisis at fly-half with Dan Biggar also receiving treatment for a rolled ankle that forced him to withdraw from the team for Wednesday's 17-13 defeat by South Africa 'A'.
Four Irish men start Saturday - Robbie Henshaw at centre makes his first appearance since the curtain-raiser against Japan on 26 June after finally overcoming a hamstring complaint, Tadhg Furlong at tighthead prop, with Tadhg Beirne andd Jck Conan teaming up in the back-row.
And in a dramatic twist, Alun Wyn Jones is included on the bench following his stunning recovery from a dislocated shoulder.
Jones' selection comes just hours after Gatland said he would not be available to face the Stormers having only returned to the Lions squad on Thursday.
