Worcestershire are hopeful Pakistan paceman Sohail Tanvir can finally link up with the county for their Twenty20 campaign this weekend.
Tanvir was initially due to be available for the entire 10 group matches as a replacement for compatriot Saeed Ajmal.
But he was then called into Pakistan's squad as an injury replacement for the one-day internationals in Sri Lanka.
Then his arrival at New Road was delayed while his visa was being processed in Islamabad.
Worcestershire chief executive David Leatherdale said: "We are now just waiting for the visa to be rubber-stamped in Pakistan.
"As soon as that happens, Sohail can jump on a plane straight away and be here.
"If that happens imminently, which we believe is the case, he will hopefully be here in time for the game at Somerset on Sunday.
"The delay is frustrating but we have no control over what happens several thousand miles away.
"If Sohail is here for Sunday, it would still mean he could play in the remaining group games."
