Dons sign keeper Fisher from Blackburn Rovers

The 21-year-old stopper spent the first half of the season on-loan up the M1 at Northampton Town, where he made three appearances for Cobblers in the Leasing.com Trophy.

"I'm really pleased," said manager Russell Martin. "We went through a list of keepers over the month and Andrew is the one Dean really wanted. We fought off a lot of competition for him as well from League One and League Two clubs. He comes in with really good pedigree. People at Blackburn speak really highly of him, so I think he will be a good addition."

Fisher has been brought in to offer competition for Lee Nicholls. Stuart Moore has been the regular number two this season, but looked out of sorts in his last appearance - the 3-0 defeat to Newport in the Leasing.com Trophy - earlier this month, and Fisher is expected to come in and challenge the pair.

Martin said: "(Fisher) will be good competition for Lee, and Lee knows he has to maintain his levels of performance. After that, it's up to Andrew to make sure he trains well to put himself in the frame to play.

"Lee has the shirt at the moment because he has done well, really well in the last few games in particular. It's up to him to maintain it and keep the jersey. Andrew will come in and battle with the other goalies to makes sure he's in the squad on a matchday."
