April 14 (Reuters) - Blessing Muzarabani has been banned from the Pakistan Super League (PSL) for two years after ​the Zimbabwe fast bowler joined Indian Premier ‌League (IPL) side Kolkata Knight Riders, despite having agreed to play for PSL team Islamabad United.

The 29-year-old, who went ​unsold in the IPL and PSL auctions, ​was signed by Islamabad but he chose ⁠to play for Kolkata instead, as the ​IPL franchise's replacement for Mustafizur Rahman, who was released ​following instructions from the Indian Cricket Board (BCCI).

The IPL and the PSL have been held almost simultaneously since last year, ​making it impossible for an international player ​to participate in both leagues.

"Despite a clear offer and an ‌unequivocal ⁠acceptance of essential terms, the player chose to disregard these obligations in favour of a conflicting arrangement," the Pakistan Cricket Board (PCB) said in a ​statement on ​Tuesday.

"The attempt ⁠to move away from such commitments without valid cause is a violation ​of contractual obligations and principles of ​good ⁠faith that govern global professional sports."

South African bowler Corbin Bosch, who last year snubbed Peshawar Zalmi ⁠to ​play for Mumbai Indians in ​the IPL, was banned from the PSL for one year.
