Arafat has played six one-day internationals, the most recent against India at Karachi in February.
He has plenty of experience against county sides, having played in the National League for the Scottish Saltires in 2004/05.
Blessed with deceptive pace and athleticism in the field, Sussex signed the talented Pakistan international midway through the 2006 season as a replacement for compatriot Rana Naved-ul-Hasan.
He impressed immediately, with both bat and ball, taking 41 wickets in eight matches and averaging 43.33 with the bat in the county championship to carry Sussex to the title. He also took 16 wickets in the Twenty20 Cup.
He left Sussex for Kent at the end of the 2006 season and helped his new county to the Twenty20 Cup in 2007 when he took 14 wickets in the competition.
He took a further 27 wickets in the county championship and made 369 runs, including a top score of 122 - one of two hundreds he scored.
An injury-hit 2008 campaign in which he took 38 wickets in 12 championship matches saw Kent relegated, and Arafat suffered the same fate with Sussex the following season.
However, relief came in the form of Twenty20 Cup and NatWest Pro40 glory, with Arafat playing a key role in both.
