West Ham United can confirm that the FA Cup with Budweiser third-round tie at Sheffield Wednesday will take place on Sunday 8 January 2012, kick-off 3pm.
The fixture has been moved back 24 hours on police advice to avoid a clash with the third-round match between Sheffield United and either Salisbury Town or Grimsby Town.
Following discussions between the two clubs, the Hammers are pleased to confirm that all Adult tickets will be priced at £20, while all concessions will be priced at £10.
Manager Sam Allardyce is looking forward to leading West Ham into the world's most-famous knockout competition for the first time.
With the Owls flying high in the npower League One table, Big Sam is relishing the prospect of a good, old-fashioned cup tie.
"Sheffield Wednesday are near the top in their division and we've all seen that there is little difference between the top of League One and the Championship by the achievements of Southampton, Brighton, Leeds, Norwich and Swansea," the manager told West Ham TV.
"Those teams at the top are generally very well-equipped to play in the Championship when they get up and I don't see any difference with Sheffield Wednesday. The experience that Gary Megson has got and the players he has put together and moulded into a successful winning team will present us with a hugely difficult task."
While Big Sam chose to blood the likes of Callum McNaughton, Pablo Barrera, Junior Stanislas and Frank Nouble in the Carling Cup defeat by Aldershot Town in August, the boss is eager to achieve a better performance and result in the Steel City.
"At that stage of the season, coming off the Christmas period, we have to see what the availability of the players is going to be like. The FA Cup is always a huge competition but it's not the major factor for us in terms of what we want to do, at the end of the day.
"Saying that, it's a competition we want to progress in after the disappointment of being knocked out in the early rounds of the Carling Cup. The good thing about that was that it taught me about players who actually, in the end, didn't prove themselves to be good enough for West Ham United. We moved a few of those on, which was very important.
"This time, when it comes to the FA Cup, we will know about everybody we're going to select in that game and we'd expect them to go out and play to their best and get us through to the next stage."
West Ham and Sheffield Wednesday have met three times previously in the FA Cup - the first occasion being a 1-0 first-round defeat at Hillsborough in January 1921.
The other two meetings both took place in the 1980s - a 2-1 sixth-round defeat at Hillsborough and a 2-0 fifth-round replay defeat at the Boleyn Ground following a 1-1 draw in Yorkshire.
The Hammers also visited Hillsborough for their FA Cup semi-final in March 1964, when a 65,000-strong crowd cheered them on to a 3-1 victory over Manchester United en route to lifting the trophy for the first time in the club's history.
West Ham have won the FA Cup three times - in 1964, 1975 and 1980 - and finished as runners-up in 1923 and 2006. Sheffield Wednesday lifted the trophy in 1896, 1907 and 1935 and were runners-up in 1890, 1966 and 2003.
In the event that a replay is required, it will be played at the Boleyn Ground on Tuesday 17 January 2012, kick-off 7.45pm.
