Hearts have announced the return of goalkeeper Craig Gordon. on a two-year contract.
The 37-year-old has rejected the offer of a new contract at Celtic to rejoin the club he started his career with.
It marks Robbie Neilson's first signing for the Tynecastle club since he rejoined earlier this month from Dundee United as his side prepare for an assault on the Championship title.
Gordon left Hearts for Sunderland in 2007 for £9million, a British record for a goalkeeper at the time.
He spent five years at the Black Cats although struggled with injury problems that led him to spend two years without a club.
Gordon then joined Celtic in 2014 under Ronny Deila and he penned a farewell on Sunday night.
He said: "The club, for initially taking a chance on someone who hadn’t played in nearly three years. And to Woodsy for encouraging me to make the move in the first place, and for training me ridiculously hard ever since. I’ve had the pleasure of playing alongside some brilliant team-mates - who without, my time at the club would have been very different.
"The fans, for their support. Home, away… all over the world. Thank you.
"My family, who have been there through it all. The ups and downs, the miles, the sacrifices, the celebrations. I hope I’ve made them proud.
"At 37, and with a few years in me yet, I just want to play the game I love, and have played for 20+ professional seasons. Football can make for difficult decisions, but I’m looking forward to the next chapter and challenge.
"Thank you, again."
