Olympic bronze medal winner David Price is unsure where his career will go, after suffered a stunning knockout defeat against German heavyweight Erkan Teper in Ludwigsburg on Friday night.

The Liverpool heavyweight was hoping to get his career back on track in only his second bout in 13 months, but his bid for the vacant European title was ended in violent fashion inside two rounds.

Teper was already having plenty of joy against Price when he connected with a massive left hook and sent the 32-year-old to the canvas. Price appeared to be out cold before he landed and, looking dazed, had to be treated in the corner before eventually rising to congratulate the unbeaten Teper, who improved his record to 15-0 with a 10th knockout victory.

The defeat is the third of Price's professional career, the other two having come in a pair of knockout defeats by America's Tony Thompson in 2013.

"I just want to apologize to my team, my family, my friends, my supporters and all who came out to Germany to get behind me. I will have to have a long think about the future. Talk with all my people and the family, but it is too early to come to a proper decision at this moment," Price said.
