Why is Quinton de Kock not playing against Sunrisers Hyderabad in Mumbai?

Quinton de Kock has missed today’s match against Sunrisers Hyderabad in Mumbai. Hardik Pandya confirmed that Ryan Rickelton will replace him in tonight’s fixture. Mumbai Indians captain Hardik Pandya won the toss and elected to bat first against Sunrisers Hyderabad at the Wankhede Stadium in Mumbai.During the toss, Hardik Pandya confirmed that Quinton de Kock sustained a hit on his wrist during practice:''We're going to bat first. Looks like a good, breezy day, as you mentioned, slightly cold compared to generally. I don't think dew will be a factor, we're gonna keep in mind and we're just gonna bat and see how much we can score. Mitchell (Santner) was unfortunate, and so was Quinny today. He just did something to his wrist. We have a couple of changes for this team. Ryan (Rickelton) comes in place of Quinny. We've got Robin Minz,'' Hardik during toss. De Kock’s absence is a significant loss for Mumbai Indians at the top of the order, given his experience and ability to provide quick starts. The wicketkeeper-batter reportedly injured his wrist during the nets, forcing a last-minute change.Mumbai Indians (Playing XI): Ryan Rickelton(w), Will Jacks, Naman Dhir, Suryakumar Yadav, Tilak Varma, Hardik Pandya(c), Robin Minz, Trent Boult, Jasprit Bumrah, AM Ghazanfar, Ashwani KumarSunrisers Hyderabad (Playing XI): Abhishek Sharma, Travis Head, Ishan Kishan, Heinrich Klaasen, Salil Arora(w), Nitish Kumar Reddy, Pat Cummins(c), Harsh Dubey, Sakib Hussain, Praful Hinge, Eshan MalingaMumbai Indians Impact subs: Mayank Rawat, Raghu Sharma, Shardul Thakur, Krish Bhagat, Raj BawaSunrisers Hyderabad Impact subs: Smaran Ravichandran, Aniket Verma, Liam Livingstone, Shivang Kumar, Harshal Patel
