Joseph also in form
So it would be interesting to see whether the Antigua-born Joseph and the big-hitting Pollard can carry their form into Saturday's game.
Another West Indian who would be in focus is Jofra Archer, who had given Rajasthan Royal a chance to defend 151 against Chennai Super Kings last night with a superb spell of fast bowling.
Mumbai are currently placed at the third spot with four wins from six matches, while Rajasthan are languishing at the seventh position with a solitary win from six matches.
Rohit's injury had given a scare to India ahead of the World Cup but Pollard has made it clear that the skipper missed the last game just as a precautionary measure and he should be back in the next game.
Rohit's inclusion will not only put to rest any doubts about his fitness but also boost the Mumbai's batting line-up, which also comprises Ishan Kishan, Hardik Pandya, Krunal Pandya and ever-reliable Surya Kumar Yadav.
Stokes has to fire
Rajasthan would be wary of MI's attack after they were reduced to a 53 for three by CSK last night. None of the batsmen could score a big innings with Ben Stokes emerging as the top-scorer with 28 run.
Royals' batting line-up, including skipper Ajinkya Rahane, Sanju Samson, Steve Smith and Jos Buttler will need to pull up their socks to confront the Mumbai bowlers at the Wankhede Stadium. Archer had a decent outing against Chennai Super Kings and his performance would also be key as well as that of Stokes.
Pressure on Unadkat
Royals pacers Jaydev Unadkat and Dhawal Kulkarni along with Shreyas Gopal and leggie Riyan Parag would have to deliver for their skipper if they have to stay alive and make it to the play-offs.
English all-rounder Stokes, who was hit for a six by New Zealand's Mitchell Santner to seal the four-wicket win for Chennai, will have to come up with something special with both bat and ball.
