Connacht have re-signed Eoin Griffin from London Irish, while Tiernan O’Halloran has agreed a new deal with the province.
Centre Griffin, who is currently recovering from a bicep tear, joined the Exiles in 2014 and has played 15 Premiership and five Challenge Cup games.
The 25-year-old, who has agreed a two-year contract, previously made 71 appearances for Connacht, including 11 in the Heineken Cup between 2009 and last year.
The Barna native said: "I'm delighted to be coming home to Connacht Rugby. I've had a great time here with London Irish and I am committed to recovering from this injury so I can finish out the season well with them.
"London Irish is definitely moving in the right direction and it wasn't an easy decision to leave but the opportunity to move home to Connacht was something I couldn't say no to.
“I'm a Connacht man born and bred, it's where my family and friends are and so it will always be home to me."
Meanwhile, versatile back O’Halloran, 24, has also signed a two-year extension with Pat Lam’s side.
