French authorities confirmed Sala was on board a single-engine Piper PA-46 Malibu aircraft flying to Cardiff when the plane disappeared from radar about 20km north of the island of Guernsey on Monday night.
Nantes' Coupe de France fixture against Entente SSG, which was set to be played on Wednesday, has been postponed. However, the Jersey air traffic control (ATC) lost contact with the plane, while it was flying at 2,300 ft.
"The search was terminated at 02:00, with all search and rescue assets being stood down, due to strengthening winds, worsening sea conditions and reducing visibility".
Authorities made a decision to suspend the search and rescue operations after the sunset around 5 p.m. local time.More news: Donald Trump says Nancy Pelosi was 'very rigid' during shutdown

The Argentine was expected to sign a three-and-a-half-year contract and join his new teammates for practice Tuesday, but the apparent tragedy now has rocked Cardiff City.
Police said they had seen a number of floating objects in the water on Tuesday, but had been unable to determine whether they were from the missing aircraft.
They wrote: "280sq. miles of our targeted search pattern using multiple aircraft from the Channel Islands, France and United Kingdom has been completed over the last five hours".
Authorities said Tuesday they did not expect to find any survivors, but the latest search is focused on possibly finding a life raft.
The statement read: "We were very shocked upon hearing the news that the plane had gone missing". Guernsey Police said search efforts would resume at sunrise but the chances of passenger survival were "slim". Sala told a group of close friends "I am now aboard a plan that seems like it is falling to pieces" adding later he was "scared". He has scored 42 goals for the squad since the 2015-16 season, including 12 goals in 19 appearances for Nantes in France's Ligue 1 this season.
