Pakistan middle-order batsman Umar Akmal has been suspended under an anti-corruption rule, the PCB announced on Thursday.
The indefinite suspension imposed on Umar sidelines him from the Pakistan Super League pending an inquiry.
The 29-year-old has been embroiled in various controversies over the course of his 11-year career, often receiving fines and punishments for disciplinary violations.
With the details about the latest case yet to be revealed, the PCB said Umar had been suspended and would not be allowed to take part in the fifth edition of the PSL, which starts today in Karachi.
"He cannot take part in any cricket-related activity pending the investigation being carried out by PCB's anti-corruption unit," the board's statement read.
"As this is an ongoing investigation, the PCB will not make any further comments."
Umar was expected to turn out for defending champions Quetta Gladiators in the six-team PSL tournament.
In response to the announcement, the franchise declared that the PCB was "already investigating the matter of Umar Akmal" it would "not make any comment until the inquiry is concluded". Meanwhile, they will take the replacement pick soon.
Umar has donned the national jersey in 16 Tests, 121 ODIs and 84 T20Is since making his debut in 2009.
His last appearance for Pakistan came during the T20I series against Sri Lanka a few months ago, where he made golden ducks on both occasions.
Earlier this month, Umar landed in trouble with the PCB after he allegedly exposed himself to a trainer following a failed fitness test.
He was severely reprimanded for his actions and the PCB termed the whole episode as a big "misunderstanding".
Umar also had run-ins in the past with former Pakistan head coach Mickey Arthur, who sent him home in acrimonious circumstances after he failed a fitness test just weeks ahead of the 2017 Champions Trophy.
