Brisbane Bullets basketballer Harry Froling is recovering in hospital after allegedly getting knocked unconscious during a night out in Wollongong over the weekend, as police arrest a 19-year-old man in relation to the incident.

Police were called to Crown Street at around 2:40am on Sunday following the Bullets' NBL away game against the Illawarra Hawks.

The 24-year-old centre, who played in the game, was discovered unconscious on the footpath and taken to Wollongong Hospital.

Froling discharged himself later that morning before flying back to Brisbane where he attended Prince Charles Hospital.

Subsequent scans reveal Froling suffered a serious head injury and he remains in hospital.

Police said initial inquiries suggested Froling had been punched in the head and knocked to the ground.

A 19-year-old man today turned himself in at Wollongong Police Station and was arrested.

Froling to miss remainder of season

The Bullets released a statement confirming Froling would not play again this season.

"The Brisbane Bullets are working closely with NSW police and NBL integrity unit as they investigate the circumstances surrounding an alleged assault on Harry Froling.

"Harry is currently recovering from an incident that occurred following the team's away game in Wollongong and will miss the remainder of the NBL23 season.
