Jordan Lukaku's proposed loan switch from Lazio to Newcastle United has collapsed, reportedly because of medical reasons.

The Belgian defender underwent a medical with the Magpies on Friday and was expected to be unveiled by the club at some point this weekend.

Newcastle have announced that Lukaku will not be joining this month, however, and the 24-year-old - brother of Manchester United's Romelu - will now return to Italy.

"Newcastle United can confirm that Jordan Lukaku will not be joining the club," a club statement read. "The Belgian defender was on Tyneside on Friday after being given permission to travel by his current club, SS Lazio.

"It has now been decided that a loan deal will not be pursued and the player will return to Rome. We wish Jordan all the best for the future."

According to Sky Sports News, the move did not collapse because of financial concerns, but more because of an issue that was flagged in his medical.

Lukaku has appeared seven times for Lazio in Serie A this season, six of those outings coming from the bench.
