The 20-year-old Polish keeper, who joined Paul Peschisolido's League Two side on an emergency loan deal in August, will now remain on loan at The Pirelli Stadium until 2nd January 2010.
"I'm delighted to secure Artur at the club until January," former Blues striker Peschisolido told the official Brewers website.
"He's been excellent since joining us and I was keen to retain his services on a longer contract.
"I'm very happy that today we have been able to do that."Debut Apps (+ sub) Goals Yellows Reds 15 Aug 2009 4 (0) 0 0 0 23 May 2009 1 (0) 0 0 0 25 Oct 2008 2 (0) 0 0 0 09 Aug 2008 2 (0) 0 0 0 16 Feb 2008 3 (1) 0 0 0 First App. Apps (+ sub) Goals Yellows Reds 15 Aug 2009 4 (0) 0 0 0 09 Aug 2008 5 (0) 0 0 0 16 Feb 2008 3 (1) 0 0 0
