The Northants Steelbacks have missed out on the chance to sign signed South African pace bowler Juan Theron because of problems with his work permit.
"The ECB initially issued a Great British entry visa and then decided it wasn't going to happen," Coach David Capel told BBC Radio Northampton.
"We're disappointed because we think he would've been a very fine player for us in that competition."
Theron has played 31 Twenty20 matches; taking 32 wickets at an average of 23.18. His full and straight style has earned the seamer a measly economical rate of 6.38.
