Zat Knight moved to the Reebok in July 2009, on the same day Wanderers also swooped for Sam Ricketts.
Standing at six foot six inches tall, Knight has nine years worth of Barclays Premier League experience, having gained promotion from Division One with Fulham in 2001.
The former England U21 international made a total of 181 appearances for the Cottagers, before moving to Aston Villa in August 2007, where he marked his debut with a headed goal against Chelsea.
The defender has also received full international recognition with England, earning caps against USA and Colombia in 2005.
Knight joined a trio of ex-Villans in Jlloyd Samuel, Gavin McCann and Gary Cahill at the Reebok.
