Cardiff plays in England's second-tier division. Cardiff is eighth among the division's 24 teams.
Cardiff is one of six Welsh sides playing in the English league system. Founded in 1899, the Bluebirds have a rich history that includes 22 Welsh Cups and one Football Association Cup. The Bluebirds became the only team to have taken the FA Cup out of England with their victory over Arsenal in 1927.
Cardiff's roster is highlighted by striker Cameron Jerome, 19, a member of England's under-21 national team who is tied for second in the division with 18 goals.
Tickets go on sale Wednesday through Ticketmaster.
