Ireland will confirm at lunchtime today if centre Gordon D'Arcy and flanker Peter O'Mahony have won their fitness battles for Sunday's RBS 6 Nations clash with England at Aviva Stadium.
D'Arcy and O'Mahony suffered a dead leg and concussion respectively in the 30-22 victory over Wales, but their rehabilitation since has been encouraging and coach Declan Kidney is expected to name the same starting XV.
Substitute centre Keith Earls is also a doubt because of a shoulder problem while centre Brian O'Driscoll, flanker Sean O'Brien, full-back Rob Kearney and prop Mike Ross have overcome knocks.
Sunday's match is being billed as an early Six Nations title decider, with recent history between the two teams pointing to an eventful afternoon.
Two years ago England saw the final leg of their Grand Slam end in a 24-8 mauling before putting Ireland to the sword 12 months later in a 30-9 triumph at Twickenham.
Munster second row Donncha O'Callaghan played in both matches and is hungry for revenge after last season's capitulation.
"Our changing room has changed a lot, even since last year at Twickenham," he said.
"Motivation is different for different fellas. Some guys want to play well so that they can be the next rock star, while other guys are driven by the motivation of playing England.
"Personally, last year left a scar that hurts and you'd love to put it right."
