Glamorgan will be without overseas star Marcus North for the first month of the season as his wife is expecting their second child.
It is another blow for the county after last year's overseas player
Alviro Petersen will not be coming back as a Kolpak signing.
"Marcus North and wife, Jo, are expecting their second child, in April of this year," a county statement said.
"Marcus will not join up with the squad until late April/early May."
Added the statement: "The club are pro-actively working to sign a temporary overseas player to cover his period of absence."
Favourite to fill that role would be North's fellow Australian Mark Cosgrove, who has had various spells at the club.
Glamorgan are set to need need someone for the first five games of the campaign.
