David Martin is growing more frustrated with every match he misses, said his manager Karl Robinson.
The goalkeeper hasn’t been seen between the sticks for Dons since the 1-1 draw in Carlisle at the end of February, suffering a back injury.
The man himself expected to be back in goal for the visit of Tranmere Rovers two weeks ago, but a reoccurrence of his injury put back his return.
Robinson said his medical staff are now trying new methods to get his number one keeper back to full fitness.
“He’s frustrated,” Robinson said. “He felt he was close to the Tranmere game but he had a relapse.
“We’re trying a different method of treatment to try and improve it.”
But in Martin’s absence, Ian McLoughlin has showed signs of a good future ahead of him, putting in some positive performances in Martin’s absence.
Robinson said: “He’s still very young, and he still makes decisions of a young goalkeeper, but you can’t knock that.
“He’s grown into the position and he has shown why we signed him. He’s a wonderful asset to the club.
“He wears his heart on his sleeve. Sometimes he speaks and needs to think a little bit more!
“I sometimes forget how young he is in goalkeeping terms. He will mature in time, and he already has the attributes of a top goalkeeper.
“He’s got the height, and his communication, his kicking and his handling are all strong.”
