Chelsea have confirmed shirt sponsors, Three, will resume their activities with immediate effect.
The UK-based company suspended its operations following Roman Abramovic's sanctions by the government following Russia's invasion of Ukraine.
Three’s partnership with Chelsea began in 2020 and their logo has been on the Blues' shirts during a highly successful period.
The men's team won the Champions League and were crowned world champions, while the Chelsea Women secured the domestic quadruple and a league and cup double in that time.
John Rogers, Chelsea Football Club’s head of global partnerships, said: "Following the recent pause in their activities, the Club is pleased to have resumed our work with Three and we look forward with excitement to the start of the new season, together.
"We would like to thank all Club partners for their support now and in the future,"
Chelsea will resume pre-season training this coming month ahead of August's kick-off.
