Bangladesh wicketkeeper Litton Das and Pakistan batter Mohammad Rizwan got into a heated argument on the fourth day of the Sylhet Test, needing intervention from on-field umpires Allahuddein Palekar and Richard Kettleborough.
The incident started in the 72nd over of Pakistan's chase, when Rizwan was gesturing at someone near the sightscreen at the pavilion end. Litton asked why he was taking so much time, which kicked things off. Rizwan walked over to umpire Kettleborough, who spoke to both Rizwan and Litton to calm things down. But it had the opposite effect as the Bangladesh fielders got involved.
At least three Bangladesh players made comments - mostly in Urdu or Hindi - about Rizwan's infamous "acting" incident after the exchange, adding to a series of flashpoints between the teams during the two Test series.
"There is going to be a 50% fine for overacting. Look now he has scored some runs, here comes the acting," was the general theme of Bangladesh's sledging of Rizwan.
Bangladesh's fast-bowling coach Shaun Tait later said he did not mind a bit of sledging. "I don't know what was said but I enjoy it (sledging)," Tait said. "I mean I'm Australian. That probably says it all. I love it. I think there's got to be some argy-bargy. Not all the time.
"You don't want to cross the line, but you got to have a bit of aggression. I mean it's a Test match between Pakistan and Bangladesh. I think the fans want to see some passion in the game. Guys in a contest trying to get each other out.
Litton's quip about Rizwan playing under pressure during the tense fifth day of the Dhaka Test also went viral on social media: "They will try to save the game. They can't win here. He doesn't have a great reputation back home," Litton had said. "If he gets out trying to hit a big one, he can't enter his country."
On the third day in Sylhet, Shan Masood and Mushfiqur Rahim clashed, after which Saud Shakeel and Taijul Islam also had an argument.
"They had also been fielding for a long time, so they probably could not control their temperament," Taijul had said at the end of the third day's play. "Mushfiq bhai did not say anything; he was just talking to the umpire normally. But whatever he [Shan] understood or did not understand, he reacted. When I was walking back to the crease, Saud told me to return to the crease and bat. I mean, that's none of his business."
There were also instances of Mohammad Abbas trying to get under Mominul Haque's skin, while Nahid Rana warned that if he was bounced while batting, he would respond with bouncers when bowling. "I just want to say that if someone bowls me a bouncer, I will not back down," Rana had said at the end of the second day's play.
Bangladesh and Pakistan players have traditionally enjoyed a healthy relationship, and while these altercations may not change that, it has added spice to another Test headed for a fifth-day finish.
