The reality stars, who appeared on series three of MTV's dating show together, had been partying alongside Love Island's Omar Sultani and Josh Ritchie when the incident took place.
According to the boys' social media accounts, both Jordan and Rogan were hit by a bottle thrown by a fellow club-goer.
According to reports, Rogan had documented the aftermath on Snapchat, showing off a cut to his eyebrow and beneath his eye. He added the caption: "Got bottled LOL."
Jordan also publicly spoke out about the incident, directing his tweet at the person who had thrown a bottle at him. He tweeted: "Shout out to the lad who through a bottle at me cos ur bird was chatting to me.. & as you did that I did take her home with me #SozNotSoz (sic)."
Jordan's tweet followed his post of a photo of himself and Rogan. He told fans he was in Derby with his former co-star, but the incident is thought to have happened at a nightclub in Birmingham.

Rogan also took to Snapchat again yesterday (2 May), sharing a new selfie with his followers. In it, his injury can be seen while he poses for the camera.
When a Twitter user joked that Rogan had been "milking his cat scratch", he replied: "Ahaha Oi stop it man.. It really hurts."
He and Jordan are believed to be ok following the incident. A rep for Rogan told Reveal that it had been a "random and unprovoked attack." They added: "Rogan is fine and in good spirits. He had to go to hospital and have stitches so will probably be left with a nasty scar but he said 'it adds character.'"
Their night out comes after Jordan has been out of the country recently. He took a hiatus from social media for three weeks, sparking speculation he has been filming for the new series of Ex On The Beach.
While many fans had hoped for Rogan's return too, he appeared to rule it out by confirming his relationship with new girlfriend Chloe Francis. He and Chloe went public with their romance in March.
