Ugandan-born Sekajja, who signed a two-year professional deal with the Eagles in June 2011, joins the Dons in time for tonight’s fixture with Leyton Orient at stadiummk, where he is set to make his debut.
Manager Karl Robinson has been open about his desire to bring in a forward with natural pace in recent weeks and he appears to have got his man in the 20-year-old.
The Dons boss told mkdons.com: “We have been looking at Ibra for some time now, he is a player who has come on leaps and bounds at Crystal Palace in the last few months.
“I spoke to Dougie Freedman on a number of occasions about him because he’s exactly what we need in the team at the moment – he is young, fearless and fast.
“We watched Ibra play against Middlesbrough’s development team on Monday night and I am delighted Ian Holloway has allowed one of his starlets to join us for the next two months.”
Sekajja will be eligible to play in the clashes against Orient, Sheffield United, Tranmere Rovers, Shrewsbury Town, Colchester United, Brentford, Hartlepool United, Doncaster Rovers, Walsall and Coventry before playing his final game away at Notts County on New Year’s Day.
He will also be eligible to play in the FA Cup Second Round Proper should the Dons get there but will not be able to feature against Cambridge City on Tuesday night, due to not being registered for the initial tie last week.
The 5ft 11in speedster came through the youth set-up at Palace, netting over 20 times for their Under-18 side before making his first team debut in the South London outfit’s 1-1 draw with Hull City in April 2011, where he scored the equaliser with his first touch in professional football.
Sekajja then joined Kettering Town on a one-month loan the following September, where he made two appearances for the then Blue Square BET Premier side.
The highly-rated forward then joined Bromley a youth-loan in December before being recalled to Selhurst Park by boss Dougie Freedman with five appearances under his belt for the Ravens.
After returning to his parent club, Sekajja went on to make one start for the claret and blue outfit, as well as making one appearance from the bench at the end of the 2011/12 season.
Sekajja, who has scored two goals in seven appearances for Palace’s U-21 side this campaign, will wear the number 28 shirt during his time at MK1.
