In March 2009, a second-half penalty from David Cotterill rescued a point for the Blades in a tough clash with Blackpool.
A Danny Coid own goal gave United the lead early on, but defensive errors handed the Tangerines the advantage with Nick Blackman and DJ Campbell getting on the scoresheet.
Cotterill levelled with his second consecutive penalty after Rachubka hauled down Jamie Ward, but despite their best efforts the home side couldn't find a winner in the gloom of Bramall Lane, following a pre-match floodlight malfunction.
