THE PBA Commissioner's Office has summomed Cagayan Valley coach Alvin Pua, a day after he punched a referee during the Rising Suns' D-League Foundation Cup game against Livermarin on Thursday.
Pua has been asked to appear before commissioner Chito Salud at 2 p.m. at the PBA office in Libis, Quezon City on Friday as the league investigates one of the worst incidents to mar the developmental league.
The Rising Suns coach has been previously banned three games and fined P50,000 for 'physical contract' with a referee last December and, before that, was penalized for punching a referee in a non-sanctioned tune-up game.
However, the latest incident is expected to be dealt with more decisively by the league office.
Pua, who league officials said punched referee Ben Montero in the first face after issuing a warning on the Cagayan coach late in the second period, had previously snubbed summons to appear before league officials.
According to Cagayan team manager Frederick Collado, Pua lost his cool over the 'arrogant' demeanor of the referee as well as bad calls which he described as 'inter-barangay' level.
