STEVIE AITKEN has wasted no time in building his Dumbarton squad with the unveiling of two new signings.

Following on from Ian Murray's departure for St Mirren last week, former Stranraer boss Aitken was unveiled at The Rock as the man to take the Sons forward over the next two years.

And, after just a day in the job, the new manager has already been hard at work, tying up Gregor Buchanan and Grant Gallagher.

Having started his career in the Junior ranks at Armadale and Bathgate Thistle, Falkirk-born defender Buchanan went on to sign for Airdrie in 2012, making over 60 appearances before landing a move last term to Dunfermline.

After being released by the Pars, he has now penned a one-year deal with the Sons.

Aitken said: "Gregor will be a welcome addition to the squad and I'm delighted to have him at Dumbarton. A lot of clubs were after him following his departure from Dunfermline, so this is a good start."

Buchanan is joined at the Championship club by Gallagher, who has followed his manager up the road from Stranraer.

Another to sign a one-year deal, the midfielder started out at as a Celtic trainee before arriving at Stair Park almost five years ago.

Aitken added: "Grant is a good player and did well for me at Stranraer. He's got a great engine and will be a good asset for us in the middle of the park."

While Buchanan and Gallagher check in, Dumbarton have announced that experienced pair Mark Gilhaney and David van Zanten have been released.

Director Alan Findlay said: "Gils signed for Dumbarton in 2010 and last season made 30 appearances, scoring one goal against Hibs in the League Cup.

"Irishman van Zanten pulled on the Sons shirt 21 times in 2014/2015, but further appearances were hampered by injury.

"Everyone at Dumbarton FC wishes both players well for the future."

First-team coach Mark Spalding has also left the club.
