The latter was handed a three-year ban for not reporting spot-fixing approaches, in the PSL.
He was earlier charged with two breaches of PCB's anti-corruption code.
Kamran reiterated the his brother will challenge the ban inflicted by the Chairman of Disciplinary Panel.
Here is more.
"I am definitely surprised with the punishment given to Umar. A three-year ban is very harsh. He will definitely approach every available forum to appeal against this ban. Other players in past have got short bans for similar offences. It's a harsh punishment," Kamran said.
He was formally charged with two breaches of PCB's anti-corruption code.
As per the charge, he failed to disclose the information related to corrupt offers.
Umar later admitted that he made a mistake by not reporting the approach.
According to reports, Umar presented his own case in Monday's hearing, while PCB was represented by their lawyer Tafazzul Rizvi.
Rizvi asserted that players who were banned previously had one charge against Umar's two.
"Umar admitted to the charges but tried to justify himself and the judge also gave him a chance several times to review his position which he didn't," Rizvi said.
The charges against him fall under Article 2.4.4, which states, "Failing to disclose to the PCB's Vigilance and Security Department (without unnecessary delay) full details of any approaches or invitations received by the Participant to engage in Corrupt Conduct under this Anti-Corruption Code".
