The head injury to Hull City striker Jan Vennegoor of Hesselink is a concern says manager Iain Dowie.
The Dutchman was felled in an aerial challenge with Aston Villa defender Richard Dunne during the Tigers' 2-0 loss, knocking him unconscious and he was taken to hospital for scans Dowie explained.
"Jan was out (unconscious) for three or four minutes. He's gone for a CT scan so it's very concerning," he told Sky Sports News.
