Gloucester's Olly Morgan starts at full-back for England U21s against Ireland at Dublin's Donnybrook ground on Friday 25th February, kick off 4pm.
Joining the squad for his first cap is Worcester back row Mark Hopley who starts at number eight in place of the injured Chris Goodman. An injury to Ross Broadfoot gives Falcons fly half Toby Flood his first start as Ryan Davis moves back to inside centre.
With Northampton Saints winger Paul Diggin also not considered due to injury, Topsy Ojo of London Irish joins the replacements.
Coach Nigel Redman said: "Ireland are always very strong and physical, particularly at home. We've watched their game against Scotland and they contested the breakdown very well and that's an area we needed to be sharper in.
"There are 10 changes to the starting side that played France for various reasons but all these guys train together as a squad during the week. Experience told us that we'd need this depth and that's the reason we extended the training squad to 26 players.
"As coaches it's a great chance for us to work with different players from all the clubs and get to know more about them and keep them all in our thoughts. At this level especially you don't always know who's going to be the best in a particular position and you have to consider everyone.
"Hopley was on the bench against Ireland for us last year and was a part of the trial games against France at the start of the season. We have some outstanding talent at back row with the likes of Goodman, Seymour, Rees, Haskell and Hopley and this is a fantastic opportunity for Mark.
"Opportunities come in many ways and injuries sometimes allow us to give some players the chance to come in and show us the work they've been doing and make us pick them next time.
"Topsy Ojo is another great example. He was in the U19 squad last year and he's in the Intermediate National Academy and he's available to us for the next two years."

Speaking to GRTV after the game, Backs Coach Tim Taylor was happy with the squad as they cruised to victory over Treviso. The result wasn't in doubt, but the Cherry and Whites laboured to secure a crucial try bonus point.
Speaking to the local media this week, Gloucester Rugby centre Matt Scott is excited to take the field again as the Cherry and Whites look to build on the win in Bayonne when Treviso come to Kingsholm this Saturday.
Defence Coach Jonny Bell admitted this week that the European Rugby Challenge Cup victory in Bayonne was a welcome one, stressed that Benetton Treviso will pose a tough test on Saturday at Kingsholm but that Gloucester are determined to deliver in front of their own fans.
Motu Matu'u is looking to make up for lost time this week as the Cherry and Whites head to Basque Country to take on Bayonne in the European Rugby Challenge Cup opener. The Samoan hooker made his first appearance in the jersey last weekend, and is hoping to contribute to the team this weekend.
Gloucester's attentions turn to Europe this weekend as they travel to Bayonne for their opening fixture of this season's European Rugby Challenge Cup. Forwards Coach Trevor Woodman told GRTV that the Cherry and Whites will be aiming to top their pool as they've done for the past two seasons, but is well aware of how tough it is to win in France.
Although understandably disappointed at seeing victory slip away at the last minute, Ben Morgan said after the game at Exeter that there were plenty of positives that Gloucester could take from the game.
Speaking after a last-gasp try from Exeter earned the Chiefs a 27-27 draw at Sandy Park on Saturday, Charlie Sharples admitted to mixed feelings. The game saw him score a try on his 200th competitive appearance for the club, but the frustration from not closing out the win was clear.
Gloucester made it two wins from two outings in this season's European Rugby Challenge Cup as they outplayed Benetton Treviso at Kingsholm to win by 37 points to 8, the bonus point try coming with the final play of the game.
