This means that Stephen Ward has been deemed fit enough to start at left-back despite concerns over an ankle injury he sustained four days ago.
Shane Long also maintains his run of starting all the Republic's games in the tournament.
The team is:
Darren Randolph; Seamus Coleman, Shane Duffy, Richard Keogh, Stephen Ward; Robbie Brady, James McCarthy, Jeff Hendrick, James McLean; Shane Long, Daryl Murphy.
Kick-off in Lyon is at 2 o'clock.
