Former Republic of Ireland under-21 international Trevor Clarke is set to join Rotherham United from Shamrock Rovers.
Hoops boss Stephen Bradley confirmed at a press briefing this morning ahead of the Europa League tie with Apollon Limassol that Clarke is in England undergoing a medical with the League 1 side.
"All going well with the medical, Trevor will be going," Bradley said this morning.
"It could be done today or tomorrow.
"He's been brilliant for us, a great kid and I wish him nothing but success, and hopefully it will all work out for him.
"He definitely has the qualities, it's just a lot else has to fall into place. But I wish him the best and like I said, hopefully the medical goes OK today, and that will be him."
The Tallaght side are expected to receive around €120,000 for the 21-year-old player who was due to be out of contract at the end of this season.
