The reason behind not playing against MS Dhoni's SRH came in front, Raina told how long it would be out.

Chennai Superkings (CSK) team led by Suresh Raina was handed over against Sunrisers Hyderabad (SRH). Raina was given this responsibility because regular captain MS Dhoni did not play against Hyderabad.
Let us know that this was the first time since March 2010 when Dhoni did not play an IPL match from Chennai SuperKings. Dhoni has been out of the playing eleven after playing 121 consecutive IPL matches for Chennai.
Along with this, it is the fourth such occasion that Dhoni is not part of the Chennai Superkings team. Earlier, in the three-year 2010 IPL season, Dhoni was not included in the playing XI of Chennai SuperKings.
Suresh Raina, who played the captaincy against Sunrisers Hyderabad, told the reason behind not playing Dhoni. Raina said that Dhoni has been rested and he will be available to play for Chennai in the next match.
