This year's Murray Trophy in Glasgow has been postponed until 2021.
The third staging of the ATP Challenger tournament, part-organised by Jamie Murray, was due to take place from 13-20 September at Scotstoun.
However, the "congested international tournament calendar" in the aftermath of the enforced suspension of tennis has forced its cancellation.
"It is a shame but, after discussing it, I agree that this is the most sensible decision," Murray said.
"I'm looking forward to making 2021 the best year yet for the Murray Trophy."
