On loan MK Dons midfielder George Williams has been ruled out for around six months after he ruptured his anterior cruciate ligament.
The 19-year-old will now return to parent club Fulham after picking up the injury in the Dons' defeat to Chesterfield last week.
The Wales international had a successful operation on Saturday.
"It was one of the most difficult hours I've had as a manager. The kid means so much to me as a person and I rate him so highly as a footballer.
I went home and cried to myself because I couldn't handle it.
I wish him all the luck in the world. I promised him that I will be at his first game back - I'm counting down the days."
MK Dons have signed Crawley Town captain Joe Walsh on loan until the end of the season, with a view to a permanent deal in the summer.
The 22-year-old defender has been linked with a number of clubs, but the Dons have won the race for his signature.
Walsh could make his debut in tomorrow's clash with Chesterfield at stadium:mk.
“We’ve known about Joe for a while and I was made up when I found out we could get it done. He’s out of contract in the summer but we’ve been given the chance to get him on loan immediately.
Since Shaun Williams we haven’t had a left-footed defender and he will provide great cover at both left-back and in the centre.
He’s only 22 years of age, he trains with the Welsh national team and he’s been in the squad a few times. He also won Young Player of the Year at Crawley Town twice in a row and the main Player of the Year award last season.”
Former Wimbledon striker John Fashanu says that he will attempt to persuade MK Dons star Dele Alli to play for Nigeria instead of England.
Alli recently completed a dream switch to Tottenham Hotspur, but was immediately loaned back to the Dons for the rest of the season.
Although Alli has played for England junior teams, the 18-year-old can still change international allegiance, and Fashanu hopes that he will choose the African nation over the Three Lions.
"I will be speaking to some people at MK Dons to help patch me through to Alli. We can't afford to lose such a talented kid to England, it's better we put up a fight than to let him go, I will do my best to persuade him to switch allegiance.
I sincerely believe in years to come he will be a top prospect and Nigeria, from what I will tell him, will be his best bet at being a global international star."
Fashanu ironically chose to play for England over Nigeria in the 1980s.

MK Dons have announced the loan signing of highly-rated Manchester City striker Devante Cole.
The 19-year-old, who is the son of former Manchester United forward Andy Cole, will stay at stadium:mk until the end of the campaign.
Cole has already spent time on loan at the Dons' League One rivals Barnsley this season, scoring seven goals in the process.

He’s an exciting youngster who can play either on the wing or up-front, he’s quick and he knows how to score goals.
He’s held in high regard by Manchester City and the FA, having represented England at all levels from Under-16s to Under-19s, and I can’t wait to work with him for the remainder of the season.”

He is willing to work hard and will bring another dimension to our attacking options.”
MK Dons look set to lose free-scoring loan striker Benik Afobe, with the Arsenal man likely to complete a permanent move to Championship side Wolves.
