Stephen McManus has joined Middlesbrough on loan, according to Celtic boss Tony Mowbray.
The Hoops captain will join up with former Parkhead boss Gordon Strachan at the Riverside until the end of the season.
Mowbray said: "The ink on the contract is drying as we speak. I had a conversation with Stephen and he is looking forward to the challenge."
He added: "We wish him well, it's a club I know well and I hope he does well for them, I'm sure he will."
