Edinburgh have signed lock Sean Cox and scrum-half Chris Leck from Sale Sharks.
The pair become head coach Michael Bradley's first additions since the former Ireland captain took charge earlier this month.
Cox, 26, who can also operate on the flank, has represented England from schools to under-21 level and made 12 Premiership appearances last season.
Leck, 25, played five times in Europe with Sale and has turned out for England at under-16 and under-18 level.
"It's great news for the club that we've secured Sean and Chris and that they'll be here right from the first day of pre-season training in a couple of weeks' time," said Bradley.
"The players are used to the sort of demanding environment and competitions in which Edinburgh operate, and they'll both bring quality and appetite to their respective positions.
"We're still in the process of adding to what is already a strong squad full of international players.
"What we've got to offer is a team and club committed to continued improvement on and off the field, and it's then a case of identifying the right players and characters to contribute to that progress."
