It's been a busy week at the CID Stadium, with three in and three out for Dumbarton ahead of their game against Morton.

Christian Nade and Stuart Carswell join on deals to the end of the season, and Lewis Vaughan comes in on loan from Raith Rovers until the end of the season.

Ryan Stevenson has moved to Raith, Joe Thomson to Queen of the South and Frazer Wright is set to link up Stirling Albion.

And with Daniel Harvie extending his loan till the end of the season, Dumbarton manager Stevie Aitken was delighted to get a lot of business done early in the transfer window.

He said: “That was my whole intention [to get business done early]. The quicker we get working because we've got a disadvantage only having them for a few hours a week so we wanted to try and get them in early and get used to myself, the rest of the staff and the players and to get them in early.

“We've done that and I'm happy with the way it's gone.”

Celtic's Thomson moved to Championship rivals Queen of the South for the rest of the season, and the Sons boss was disappointed to not retain his services.

He added: “Since Joe's come in we've given him an opportunity and he'd not played first team football before.

“He's done great, we're delighted how he's got on but unfortunately he's not our player and we couldn't do too much about it to be fair because the boy wanted to train full-time which I understand.

“But that's just football and we thank him for his time and his efforts with the club and wish him well.”

In to replace Thomson is Carswell, who joins the club after a spell at Icelandic side Keflavík.

It is understood that it will be touch and go for his international clearance to come through before tomorrow's game against Morton, but should be sorted in time for their game against Hibernian next week.

The 23-year-old played for St Mirren last season, and Aitken revealed he tried to sign for former Motherwell youth product in the summer.

The Sons boss said: “He was one of the first ones I tried to sign. We tried to get a deal with him for two or three weeks, but the team from Iceland came in and he wanted to try and play abroad.

“We were aware that he was back and he's been training with us for the last few weeks and looked really good.

“We're just waiting for clearance to come from Iceland so that we can play him, and he'll be a great addition to the squad.”

Another played who left Dumbarton was Stevenson. The ex-Hearts man moved to Raith, with former Jambos player Gary Locke the manager of Rovers.

And while Aitken said he hadn't hit the heights he had hoped at Dumbarton, he provided them with key goals in his spell with the club.

The Dumbarton manager added: “He's had a terrific career. Obviously as you get older your game changes with everything else.

“He found it difficult to adjust which I get, he's been full-time all his career and then switching to part-time and training at nights, it's not easy. But he's popped up with a couple of great goals, especially the one against Queen of the South.

“The opportunity came up to go back full-time with Raith Rovers and I didn't want to stand in the players way so we wish him well and good luck to him in his career.”

Coming the other way is Vaughan, the 21-year-old signs on loan from the Stark's Park side until the end of the season, with Aitken confirming that Raith could not recall him from his loan.

He said: “When we were informed he had become available we jumped at it.

“The boy is a special talent, he's had a bit of an injury this year but before that clubs in England were looking at him.

“He's played and he's been involved, Gary Locke thinks he just needs to get out and get more games and we're delighted he's coming to us.”

Wright left the club last night, and the 36-year-old is most likely to be reunited with former St Johnstone teammate Dave Mackay, who is the manager at The Binos.

Aitken added: “Frazer's had a tough time with injuries, he's been back for the last four-five weeks and he felt it was the right thing to do and go.

“He'll go and do coaching with Stirling Albion, it's a good opportunity for him and he's been terrific for us, especially last season he was outstanding for us “But this year he's struggled as he's been injured at the wrong times, and with the form of Darren Barr and Gregor Buchanan his game time has been restricted.

“We spoke to the player tonight [Thursday] and we wish him well.”

And Harvie has extended his loan deal, with Nade also returning to the Rock after having a spell with the club last season.

The Dumbarton manager said: “Aberdeen have been delighted with how Daniel's getting on.

“I think he's got a big future in the game and if we can help him along the way then it helps both parties.

“Nade was terrific last year, and he gave us that wee bit extra that helped keep us in the division. He came back, he's been training with us for the last few weeks.

“If he can show the form that he showed last season then I think he'll be another good signing.”

And after Wright's departure this week, Aitken will be looking to sign a defender, with the manager hoping to bring someone in before the end of next week.

And likely to head out on loan from Dumbarton is Donald McCallum, the Sons academy product has not featured in recent weeks and the manager is hoping he can get some games under his belt.

Aitken said: “With Frazer Wright leaving we're a bit light in defensive cover and that's the next priority.

“We've got good attacking options and plenty of options in the middle of the park with Daniel Harvie it's given us that security.

“We're actively working away in the background, talking to agents and other clubs, talking to managers looking to see what's out there, but the Frazer situation only developed late on Tuesday.

“We're looking to get him [McCallum] some games, he's found it difficult as well especially in the last few weeks when the team has been in really good form.

“There's a few clubs interested and we'll sit down with them next week and see which one is best for Donald and try and get some games that he needs.”
