"(Itoje) is a big player who can add some light to the pack ... after 45 or 50 minutes."
Warburton would assume the captaincy off the bench, when Itoje came on for Jones.
In the big backline call, Henry says if Owen Farrell is fit, the English star should partner Welsh powerhouse Jonathan Davies in the centres.
"[Johnny] Sexton has come right and played exceptionally well," he said, adding that halfback Conor Murray was the best No. 9 in world rugby.
He would bypass struggling power wing George North, a certainty in top form but a man whose career has been hit by horrid concussion problems.
Henry includes England's Jonathan Joseph on the bench as the outside back cover, despite concerns over his defence.
He manages one big surprise on the reserves bench, nominating stoic prop Dan Cole at tighthead ahead of the impressive but inexperienced impact specialist Kyle Sinckler.
Henry finished off his selection saying: "I don't know if Warren will get that right, but I think it will be pretty close."
Henry's team is: Leigh Halfpenny, Liam Williams, Jonathan Davies, Owen Farrell (Ben Te'o), Anthony Watson, Johnny Sexton, Conor Murray; Taulupe Faletau, Sean O'Brien, Peter O'Mahony, Alun Wyn Jones (c), George Kruis, Tadhg Furlong, Jamie George, Mako Vunipola. Reserves: Rory Best, Jack McGrath, Dan Cole, Maro Itoje, Sam Warburton; Rhys Webb, Jonathan Joseph, George North/Te'o.
