Revered Indian cricket journalist Harsha Bhogle added: "How low is legal round-arm?"
Slater said: "I don't think I've ever seen anything like that before."
"(The umpire's) just telling him, 'Just be careful. You can't go any lower than that. Underarm's not allowed anymore,' as the Aussies no very well," Bhogle said.
The umpire behind the stumps was seen having a word with Parag during the over, likely reminding him of the laws.
Parag dismissed Gayle on the second-last ball of his over when the master blaster holed out to Ben Stokes at long-on, although the youngster had bowled a normal delivery to dismiss him.
