Guy Armitage has extended his loan stay at London Irish for a further two seasons.
The 21-year-old left the Exiles last year to join brothers Delon and Steffon at French heavyweights Toulon.
However he moved back to the Madejski Stadium on loan earlier this season after Irish suffered an injury crisis at centre and has since established himself as a regular starter.
That has convinced Irish to extend his loan deal and director of rugby Brian Smith is tipping the youngster to make his full England debut this summer.
"Guy Armitage is fast becoming one of the most dynamic power centres in the country," said Smith.
"He's a genuine Premiership player with the ability to go on and play for England like his two older brothers.
"Guy has forced his way into the starting team this season and if he keeps performing may well be considered for England's summer tour of Argentina."
Armitage said: "I have really enjoyed my rugby since I returned to London Irish from Toulon.
"I have come through the ranks with a number of these players and enjoy playing with them week in week out.
"I look forward to pushing on as a player and with the club over the next few seasons."
