Dhaka Metropolis medium-pacer Talha Jubair took the first eight wickets to fall in the National Cricket League match against Rangpur Division in Bogra, but he was prevented from trying for all ten because of a new rule implemented by the Bangladesh board to protect players from injury. From this season, a seamer is allowed to bowl a maximum of 15 overs per day in Bangladesh's domestic first-class tournament.
Jubair took eight wickets in an opening spell that lasted 13 overs and spanned the entire first session. His last wicket came in his 11th over, and he sought permission to bowl more overs but the match referee Hemayet Ahmed did not allow it after Rangpur turned down the request. Left-arm spinner Arafat Sunny took the remaining two wickets.
"Pace bowlers this season have been asked to bowl no more than 15 overs per day," said Hafiz Joarder, member secretary of BCB's tournament committee. "The technical committee has made this recommendation before the NCL started, and our physician has also approved of it.
"Many of our pace bowlers have had back and leg injuries in the past few seasons due to the hard grounds across the country. Not every outfield is like the one in Khulna or Mirpur."
Joarder said the BCB can enforce such a decree on the pace bowlers because it is a domestic tournament. "We can do it because it is being held domestically. We follow all the ICC rules and playing condition but we can include our own rules too."
Jubair's 8 for 35 is the best bowling figures in an innings for a Bangladeshi seamer in first-class cricket, beating Al-Amin Hossain's 7 for 37 from the 2011-12 season.
