Chennai: Chennai Super Kings (CSK) have ended their long association with former Australian batter Mike Hussey, who served as the franchise's batting coach since 2018, as part of a major restructuring of their support staff ahead of the Indian Premier League (IPL) 2027 season.

The five-time IPL champions have also appointed former England spinner Gareth Batty as assistant coach, continuing a series of changes that have seen several familiar faces depart following three disappointing seasons.

Hussey, who represented CSK for six seasons as a player before taking over as batting coach in 2018, has been closely associated with the franchise since the IPL's inaugural edition.

Announcing his departure on social media, CSK paid tribute to the former Australian international and acknowledged his contributions both on and off the field.

"From the very first season in 2008, you have been an integral part of the Chennai Super Kings family," the CSK said in their social media handles, announcing the decision to move on from Hussey.

"Your journey in Yellow has been defined not just by the runs you scored and the players you mentored, but by the dedication, humility, and unwavering commitment you brought to this franchise over the years.

"Your place in our history will forever remain special, Hussmeister. Once a Super King, always a Super King," the statement read.

Hussey's departure is among several major changes to the CSK coaching setup ahead of the upcoming season.

The franchise has also confirmed the exit of bowling coach Eric Simons, who had been associated with the team since 2018. Former India fast bowler Mohit Sharma will replace him.

In a farewell message, CSK acknowledged Simons' role in developing the team's bowling attack.

"An integral part of the Chennai Super Kings coaching setup since 2018, Eric Simons has played an important role in shaping our bowling unit and contributing to the team's success over the years.

"We extend our sincere gratitude for your dedicated service and contributions. Thank you, Eric Simons. Wishing you the very best in your future endeavours."

Assistant coach Rajiv Kumar, fielding coach James Foster and physiotherapist Tommy Simsek will also leave the franchise ahead of IPL 2027.

The extensive changes follow a difficult period for CSK, who have struggled to maintain their dominance since lifting their fifth IPL trophy in 2023.

The Chennai-based franchise finished fifth in 2024 before slipping to the bottom of the table in 2025. Although they improved slightly in 2026, an eighth-place finish added to concerns over the team's performances.

The disappointing results also brought an end to Stephen Fleming's long tenure as head coach. The former New Zealand captain has moved on to take charge of England's Test team.

Former India pacer Zaheer Khan has been appointed as Fleming's successor and will begin his first IPL campaign with CSK in 2027.

As part of the coaching overhaul, CSK have brought in former England off-spinner Gareth Batty to work alongside Zaheer Khan.

Batty, 49, represented England in nine Tests, 10 ODIs and one T20I during his international career.

He also shares a professional connection with Zaheer, having played alongside the former Indian fast bowler at Worcestershire in English county cricket.

Since moving into coaching, Batty has established a strong reputation in England's domestic circuit. He played a key role in Surrey's remarkable run of three consecutive County Championship titles between 2022 and 2024.

He also served as an assistant coach with MI London in the revamped Hundred competition.
