Chelsea sent to the Premier League a structured request that, if accepted, will make the overall number of replacements raised from seven to nine.
Chelsea’s appeal arrives in the wake of professional health issues with a lengthy break from playing raising the risk of injuries, the Daily Mail says.
The plan would be discussed with a vote on the matter expected a week later at the next shareholders meeting on Thursday.
Players have recently begun full contact practices ahead of the resumption of the Premier League on June 17. But the remaining 92 games will be compressed into a span of six weeks, which would raise workloads for teams.
