This is a list of all personnel changes for the 2018 Indian Premier League. This was the third season to have all players, apart from a selection of retained players, return to the auction pool (first in 2011, second in 2014) Player retention Retention policy The eight teams could retain a maximum of five players from their squad, out of which only three could be retained during the retention period. The teams could also use a maximum of three right-to-match cards at the auction (a maximum of two, if the franchise retained three players during the retention period). The other restrictions on player retention were: a maximum of three capped Indian players could be retained, and only two overseas players and two uncapped Indian players could be retained. The salary deduction for every retained player from the franchise's salary purse was stipulated to be 15 crore, 11 crore and 7 crore if three players were retained; 12.5 crore and 8.5 crore if two players were retained; and 12.5 crore if only one player was retained. For retaining an uncapped player, salary deduction was set at 3 crore. Chennai and Rajasthan, two franchises which were returning after serving a two-year suspension, were allowed to retain players from their respective 2015 squads who were not part of the squads of any of the other six teams in 2017. This meant that Chennai could retain from a pool of 13 players whereas Rajasthan had 6 players to choose from. Retained players The franchises were required to submit their retention lists by 4 January 2018. Player retention was broadcast live on Star Sports, making it the first time that player retention was telecasted. Auction The player auction for the 2018 Indian Premier League was held in Bangalore on 27 and 28 January 2018. The salary cap for the season was increased from 66 crore to 80 crore, with all franchises needing to spend at least 75 percent of the amount. In total 1122 players signed up to be a part of the auction. The team requested an addition of 9 players in the IPL longlist including Nepalese spinner Sandeep Lamichhane who became the first Nepalese to be listed in IPL auction. The list was shortlisted to the total of 578 players including 360 Indians. This was the first time that both capped and uncapped players were going to be auctioned on the same day.
