Edinburgh have bolstered their second row ahead of next season with the signings of Perry-John Parker and Robert McAlpine.
Parker will make the switch from RFU Championship side Esher, while Scotland Under-20s international McAlpine joins him in signing a two-year deal after initially starting last season at Glasgow Warriors.
McAlpine spent the second half of the campaign at Edinburgh, playing twice and impressing with his work rate.
Head coach Michael Bradley, said: "It's very exciting for Edinburgh Rugby to have secured two very promising young locks at crucial stages of their respective careers.
"While we'll continue to refine the expansive, attacking play for which the club is famous, we're keen to introduce a harder, more aggressive edge to our play, and believe this pair will work tirelessly to lay the platform from which our back division can play.
"Both players have real quality, are exceptionally committed, and will develop into top-class second rows for Edinburgh Rugby."
