Rock solid back row performer Kai Horstmann joined Worcester Warriors from Harlequins in May 2005 and has been an integral part of the side at Sixways Stadium.
The forward has captained the side on a number of occasions and was awarded the Player’s Player-of-the-Year at the club’s annual awards at the end of the 2005/06 season.
Horstmann repeated that feat at the end of the 2006/07 season when he was named Player of the Year and secured a dream double with both the Player of the Year and Player's Player of the Year award at the 2008/09 awards dinner.
His performances have also thrust him into the international arena with a call-up to the England Saxons for the Churchill Cup tour of North America in July 2006. He was also a member of the IRB World Sevens Series squad in 2003/2004 season.
The Number Eight made his 150th appearance for the club during the 2010/11 season, a year when he was named vice captain and captained the side in the absence of Chris Pennell.
Horstmann left Warriors in 2012 to join Exeter Chiefs.
