Fraser Aird spent part of last season on loan at Scottish Championship side Queen of the South

Fraser Aird has apologised for a "thoughtless" gesture at Celtic Park that led to his departure from Cove Rangers.

Cove said external-link Aird, 24, was leaving "with immediate effect" after footage emerged of him as he watched his former club Rangers in their 2-1 Old Firm win.

The winger's deal with the League Two side was due to end in early January.

"I have a responsibility to carry myself in an appropriate manner," the Canada player said on Twitter.

"I got caught up in supporting my boyhood club and did something thoughtless. I hope everyone will forgive me for it."

Aird joined Paul Hartley's league leaders in the summer after spells at Falkirk, Dunfermline, Dundee United and Queen of the South.

Rangers beat hosts Celtic to move to within two points of their city rivals at the Scottish Premiership summit, having played a game fewer.

Earlier on Monday, Cove said of Aird's gesture: "As a club we do not condone such behaviour and expect all of our players to represent our club in the correct manner at all times.

"Fraser Aird's contract with the club was due to expire at the start of January and as a result he will be leaving the club with immediate effect."
