Andrew Balbirnie has joined Glamorgan on a short-term contract, having spent time with the club in the second half of 2020.
The Irish skipper was given permission by Cricket Ireland to make the move, with the planned tour of Zimbabwe next month having been postponed in February.
He joins the Welsh club as the overseas player until the end of April, replacing Marnus Labuschagne who is unlikely to be available until May owing to an extended run with his club Queensland in Australia.
"It’s a brilliant opportunity to play red-ball cricket, and the County Championship is historically one of the best first-class competitions in the world," said Balbirnie.
"I really enjoyed my time in Wales last season in the Vitality Blast - the players and coaches were incredibly welcoming and it’s a great place to play. I’m really excited to go back, get stuck in and hopefully contribute to some wins for Glamorgan."
Richard Holdsworth, High Performance Director for Cricket Ireland added:
"A window of opportunity arose with the postponement of the men’s tour to Zimbabwe, and we were happy to agree to Andrew’s move for six weeks to Glamorgan. We have a big year ahead of us at both international and domestic levels, with a T20 World Cup in late 2021, so for one of our key players to be able to take advantage of an opportunity to play cricket in April at this standard will be of great benefit."
"Balbo will be back for the start of the Inter-Provincial Series campaign in early May, then will lead the senior men’s squad into action against the Netherlands in early June."
