Rauf had bowled five wicketless overs for 27 runs on Sunday before intermittent rain stopped proceedings, with India batting at 147 for the loss of two wickets in 24.1 overs.
With no overs lost despite another delay lasting about an hour and forty minutes on the reserve day, i.e. Monday, it was disclosed that Rauf had experienced "a little discomfort in his right flank" on Sunday.
"Fast bowler Haris Rauf will not be bowling any further in the Asia Cup Super 4 match against India as a precautionary measure," the Pakistan Cricket Board (PCB) said in a statement.
"He felt a little discomfort in his right flank during the match yesterday and was subsequently taken for a precautionary MRI, which revealed no tear. He remains under the observation of the team's medical panel," the statement added.
Pakistan bowling coach Morne Morkel said before the start of play: "Unfortunately, Haris started feeling his oblique muscle and went for a scan last night, which revealed inflammation. With the World Cup around the corner, we're putting him on ice today."
The rain-affected contest resumed in Colombo at 4:40pm when rain prevented the start of play at the scheduled time of 3pm.
