South Africa bowler Keshav Maharaj's move to Middlesex for the 2023 season has been ended by a "freak injury" while celebrating a wicket.
It was later confirmed Maharaj ruptured an Achilles tendon just before lunch.
"We are saddened to hear that he will face a significant absence from playing," Middlesex director of cricket Alan Coleman said.
"We are naturally extremely disappointed that Keshav will not be joining Middlesex this year after sustaining this freak injury.
"It goes without saying that everyone at the club wishes him a speedy recovery."
Maharaj has taken 206 wickets in 100 internationals and was signed to play the entire T20 Blast campaign for Middlesex and eight County Championship games, though would have missed the first two rounds.
"For us to lose Kesh so close to the start of the new season is a blow, however he wasn't scheduled to begin playing for us until late April, which buys us a little time to put plan B into action," Coleman added.
"We will, of course, keep everyone updated on the situation regarding a replacement overseas player for the coming season."
The Lord's-based county have already announced that fellow South African Pieter Malan will return for a second year and play as overseas in all competitions.
