Danny Wilson brings his Blades side across Sheffield to take on the Millers tomorrow night as the two teams meet in competitive action for the first time in well over six years.
Other than pre-season encounters, the last clash between the two was back in February 2005 as the Millers went down 1-0 at Bramall Lane in the campaign that saw them relegated from the Championship.

Team News..
Blades boss Wilson could make numerous changes to his squad but is set to play a host of regulars including ex-Millers duo Stephen Quinn and Lee Williamson.
His search for a loan player is set to come too late for tomorrow's game but United's game against Preston at the weekend has now been postponed.
Millers boss Andy Scott looks likely to draft in Ben Pringle and Andy Warrington for starts. It is still unclear if Marcus Marshall will be involved after he missed the weekend defeat at Port Vale.
Troy Brown is away with the Welsh Under 21 squad so Dale Tonge is set to come in at full back. Luke Foster may also be involved if Scott feels Johnny Mullins shoudn't be risked for the full 90 minutes as he continues his comeback from knee surgery. Ryan Cresswell misses out against his former club.
