Two of the top six in the Sky Bet Championship go head-to-head at the Cardiff City Stadium. Former Blades manager Neil Warnock is always up for it when he comes up against the Owls.
Form (Cardiff City)
Cardiff go into this game on the back of their first defeat of the season, losing 3-0 away at Preston on Tuesday night. Before this came five straight wins and a draw, which is why they are currently 2nd in the table.
Form (Sheffield Wednesday)
Sheffield Wednesday have won back-to-back games for the first time this season, both coming at Hillsborough. They beat Nottingham Forest 3-1 and followed that up with a 2-1 win against Brentford.
The Owls are unbeaten in the league since the first game of the season and have made their best start to a season under Carlos Carvalhal.
Cardiff have no new injury concerns. Neil Warnock could make several changes to his starting line-up after their first defeat in the league. New signings Liam Feeney and Craig Bryson are looking to make their first starts for the club.
Former Bluebird Glen Loovens (hip), George Boyd (shoulder), Sam Hutchinson (knee), Almen Abdi (knee) and Fernando Forestieri (knee) are all out of this game.
Steven Fletcher, Kieran Lee, Ross Wallace and Barry Bannan all have knocks and are being assessed.
Nathaniel Mendez-Laing (Cardiff City)
A free transfer from Rochdale, Mendez-Laing been one of the stars of the early season. He has five goals to his name already and is linking up well with Blurebirds striker Kenneth Zohore.
Gary Hooper (Sheffield Wednesday)
The ex-Celtic striker has four goals in all competitions this season and two in two games. Having struggled with injuries last season, he will be looking to have a long successful one this campaign.
Last time out Wednesday were the victors with a 1-0 win at Hillsborough in April 2017.
The two previous meetings in the Welsh capital have both ended as draws (2-2 in 15/16 and 1-1 in 16/17).
Cardiff are unbeaten at home against the Owls since 2007, when the Welsh team played at Ninian Park.
