Following the blanket COVID-19 testing on Monday, all tests completed on Colchester United personnel have returned negative results for the virus.
Monday morning saw all the first team squad players and staff tested, as part of the EFL's procedure to minimise the transmission of COVID-19 in football clubs across the country.
All of the forty tests, which were carried out at the JobServe Community Stadium due to deep cleaning at Florence Park, came back as negative.
Performance Director Jon De Souza was pleased with the outcome of the results, but wasn't taking anything for granted with a new lockdown in place that allows elite football to continue.
He told cu-fc.com: "Getting negative results across the whole group is fantastic because primarily the health and safety of the players and staff is of paramount importance to us."
"Secondly, it was important that we as a club are following the regulations as closely as possible because it's imperative that football is a safe place now that we are continuing through this next lockdown.
"There is light at the end of the tunnel with the vaccines being rolled out, but we have to take this positive news forward and ensure that we have similar success with any new EFL and Governmental testing procedures and protocols that will no doubt be put in place."
U's Chairman Robbie Cowling added: "Following last week's incident with a positive test, I am pleased that the COVID-19 protocols we have in place at the club have ensured that all these tests came back negative and no other players were infected."
