Brussels Terror Attack -- Pro Basketball Player Injured ... Emergency Leg Surgery

12:36 PM PT -- Oakland University coach Greg Kampe issued a statement about Seb:

"The Oakland basketball family was very sad to hear about the attack in Belgium and one of our own was in the midst of it. We send our prayers to Seb and his family."

"Seb has remained very close to our program through the years, he's in constant contact with our players and staff here at Oakland University and has been one of the biggest supporters and cheerleaders for the Oakland basketball program. One in which he led us to a championship while he was here."

"Saying that, all I can add is that I hope everybody who knows or has ever met Seb can give their prayers or do whatever they need to do for him. He is a tremendous competitor and he will fight through this."

One of the people badly injured in the Brussels terror attacks Tuesday morning is a former college basketball player who turned pro in Europe ... who just underwent emergency surgery after badly injuring his leg in the blast.

Images of Sebastien Bellin laying on the ground at the airport went viral -- his leg twisted and bleeding from the explosion.

37-year-old Bellin played college basketball at Oakland University in Michigan from '98 to '00 before heading to Europe where he's been playing pro ball ever since. He's currently a member of BC Telenet Oostende, a pro team in Belgium.

We spoke with a rep from Oakland University who tells us ... "Coach has been in contact with Sebastien's family and what we know is he injured his leg and hip and he will be okay."
