The Indian Premier League Governing Council met in New Delhi on Wednesday alongwith the Committee of Administrators (CoA) to decide the player retention policy, salary cap, player regulations and other related issues, especially for the uncapped players, with ten seasons up for the cash-rich league.
"The player pool available for CSK and RR for retention/RTM will be the players' who played for them respectively in IPL 2015 and who were part of RPS and Gujarat Lions squads in IPL 2017", he added. Dhoni had played for the Rising Pune Supergiant (RPS) in the last two seasons.
However, Rising Pune Supergiants and Gujarat Lions will not feature in the 11th edition of the tournament.
As per the governing council's decision, a franchise can retain five players using one of the two combinations - three pre-auction retentions and two RTMs or two pre-auction retentions and three RTMs.
The player auctions for the next IPL is scheduled to take place in February 2018.
In terms of squad size, the previous squad limit of 27 has been reduced to a maximum of 25 players, up to eight overseas, and a minimum of 18 players.
In the event of the franchise not retaining a player directly, they will be allowed to use their right to match thrice during the player auction. However, it was decided not more than three Indian and two foreign players can be retained by a franchise.
If there is no retention before player auction then franchises can have up to 3 RTM. Therefore, the team that retains all three players will go into the auction with a reduced purse of Rs 47 crore.
George also confirmed that they can only retain players who played for them in 2015. If only one player is retained, then he will cost the franchise INR 12.5 crore from the salary cap. The minimum spend will be 75 per cent of the salary cap for each season to aid junior players.
The auction reserve prices have also been increased, with a hike of Rs 10 lakh in the prices for uncapped players, which will now begin from Rs 20, 30 or 40 lakh.
In July 2017, The Board of Control for Cricket in India said on Friday that Chennai Super Kings and Rajasthan Royals would be back for 2018 IPL.
