Chelsea have submitted a formal proposal to the Premier League to increase the maximum number of substitutes permitted on the bench from seven to nine for the remainder of the season.
The proposal will be discussed by the clubs at this Thursday's shareholders meeting with a vote on the issue to take place the following week on 11 June.
Chelsea's request to increase the number of substitute options available to managers stems from concerns about the greater risk of injuries following a lengthy break and the prospect of cramming nine matches into a six-week period.
