@Justyrodz22 bro, Pune is unlucky to MS supporters as he himself termed Pune the same after losing an international match (in post-match presentation). Think it was between IPL9 & 10.
This is the first time Raina is going miss an IPL match for CSK. I'm not 100% sure whether he missed any matches for Gujarat Lions in the previous 2 seasons. Anyways it had to happen sometime. But with already Faf and Jadhav having injury issues, this is a big big blow for CSK.
