Defending Natwest Twenty20 Blast champions Birmingham Bears have secured the services of New Zealand captain Brendon McCullum for their final seven games of this year's tournament.
The 33-year-old's first game should be against the Lancashire Lightning on June 26 once New Zealand's tour of England has been concluded.
"The Birmingham Bears had a great season last year, including winning the NatWest T20 Blast, and hopefully I can make a big contribution and ensure that we can progress in the tournament," said McCullum.
"Edgbaston is a fantastic ground to play at and hopefully it will be rocking for the big Friday night matches. I'm really excited about becoming a Bear and the challenge ahead."
The batsman was recently named captain of the ICC Cricket World Cup Team of the Tournament after leading the Black Caps to the final.
