During Thursday’s clash, Boult had walked off the ground due to a groin strain. The left-arm pacer bowled just two overs in the match and got rid of Prithvi Shaw (0) and Ajinkya Rahane (0) in the first over itself.
"I've not seen him (Boult). But he seems okay. I don't think it's a big problem. Three-day rest and he should be back on the park," quoted Rohit at the post-match presentation ceremony.
"(Jasprit) Bumrah and Boult have been in solid form. They play for different teams so they have different plans. We as a team have different plans and it's great to see them execute those," he added.
Bumrah also starred with the ball, taking four crucial wickets to help MI thrash DC at the Dubai International Stadium.
With this victory, the defending champions have made it to the final while Delhi will face the winner of Royal Challengers Bangalore and SunRisers Hyderabad eliminator clash.
Earlier, MI rode on Ishan Kishan (55* off 30 balls) and Hardik Pandya’s (37* off 14 balls) blitz to post a mammoth 200/5 in their stipulated 20 overs.
"I guess this is the best performance. The way de Kock and SKY took the momentum after I got out early was good to see," said Rohit.
"Perfect result for us. We never had a target in mind. We are a different team and we play differently. We just wanted to have a good powerplay and then take it from there.
"We knew we have the power to accelerate at the end. Ishan has been in just great form, so we just wanted him to be really positive after the second time-out.
"We told that to Krunal as well, just bat positively and put the bowlers under pressure. With such a versatile squad, we can change the batting and bowling order," he added.
