The England and Wales Cricket Board has removed Pakistan all-rounder Shahid Afridi's registration for Hampshire, reports BBC Radio Solent.
The decision comes after Afridi's central contract with Pakistan was suspended after "disparaging remarks about the [Pakistan Cricket] Board".
Afridi, 33, will be unavailable for Hampshire's opening FL t20 match against Somerset at the Rose Bowl.
But the county are attempting to get the situation reversed.
Afridi's manager, Umran Khan, is optimistic the cricketer will be issued with a new 'No Objection Certificate' (NOC), so that he will be available to play against Surrey at the Rose Bowl on Friday.
"We're hopeful of a resolution very quickly and that he's available for the next game but it depends on the England and Wales Cricket Board (ECB) receiving another NOC from the Pakistan Cricket Board (PCB)," he said.
"We hope a resolution is not far around the corner and the PCB can provide us with a new NOC and Afridi can get on with playing for Hampshire."
