Reading have signed Swansea winger Mo Barrow on a four-year contract.
The 24-year old, who made 55 appearances for the club, joined the Swans on their pre-season tour of the US.
However, he will now join Reading before their first fixture of the Championship season against Queens Park Rangers.
Reading manager Jaap Stam said: "I'm very pleased to welcome Mo to Reading Football Club and I'm delighted that we have been able to add another player to our squad ahead of the start of the new season.
"Now all our focus is on the challenge that lies ahead on Saturday and our trip to QPR."
