King's Lynn joint boss Gary Setchell is hopeful defender Pat Bexfield will be fit for this weekend's FA Vase tie against Gorleston.

The 22-year-old is set for further hospital tests today after being detained overnight on Monday at Addenbrooke's after fainting at home. Bexfield was released on Tuesday having undergone checks for a suspected heart murmur.

'As a precaution they kept him in because he had suffered a few seizures,' said Setchell, 'They've tested for things like diabetes and every test they have done came back clear. He's been released but has to go back for a few more because they still don't quite know what is causing this. But if gets the all clear he'll be available.'

Bexfield played the full 90 minutes in Lynn's weekend 5-0 UCL romp at Irchester but complained of feeling unwell on Monday morning.

'I actually spoke to him in the hospital and he was alright,' said fellow boss Kevin Boon. 'He was right as rain and he couldn't believe it that they were keeping him in.

'He played well on Saturday and there was no sign of anything wrong but apparently he was at home on Monday morning and just felt unwell and fainted. I know he had a knock on the head earlier this year, but the doctors had checked that out and said there was nothing wrong.'

Bexfield suffered a similar reaction at former club Cambridge City.

'It's the second time this has happened in the last three months,' said Setchell. 'The first time he was doing some heading practice but there was nothing like that this time around. We were very worried when we first heard the news – firstly of course for the lad and his health – but with Jamie (Thurlbourne) out suspended and his brother carrying a knee problem he would be a big miss for the FA Vase tie.

'We tried Pat in midfield at the weekend and he was a strong and powerful player for us.'

Bexfield has turned in a string of impressive displays, mainly at right-back, since joining Lynn in the close season. The versatile 22-year-old came through the youth ranks at Norwich and was awarded a professional contract in May 2007. Bexfield never made a senior appearance at Carrow Road and was one of nine players released by former Norwich manager Glenn Roeder following the 2007/08 Championship season. Bexfield had trials at his hometown club and went on to play for Wisbech in the Ridgeons Premier before linking up with King's Lynn Town this summer.
