The incident occurred on Tuesday evening when Agarwal was travelling from Agartala to Surat via New Delhi for Karnataka's fifth-round Ranji Trophy fixture against Railways starting on Friday. Agarwal is believed to have been deplaned and rushed to hospital after a bout of vomiting inside the aircraft, even as the rest of the Karnataka squad continued their onward travel.

Agarwal is said to be out of danger, but the severity of his medical condition is yet to be ascertained. He will be under observation for 24 hours. The Karnataka State Cricket Association (KSCA) is in touch with officials from the Tripura Cricket Association (TCA) and the doctors attending to Agarwal.

He is set to undergo a few tests following which a decision will be made if he can return home to Bengaluru over the next couple of days for further examination. This all but rules him out of the upcoming Ranji fixture.

In a press statement, IndiGo confirmed that the flight had to return to Agartala due to a medical emergency: "IndiGo flight 6E 5177 operating from Agartala to Delhi returned to origin due to a medical emergency onboard. The passenger was offloaded and was rushed to the hospital for further medical assistance. The aircraft took off again for its destination at 1620h."

Agarwal has so far struck two hundreds and a half-century in the ongoing season. Karnataka are currently placed second in Group C with two wins, a draw and a defeat in four matches. Nikin Jose, the 23-year-old batter, is the designated vice-captain in the squad and is likely to take over the captaincy.
