The PBA on Thursday slapped a P100,000 fine on the Blackwater Elite for practicing ahead of the official resumption of practices.
Commissioner Willie Marcial also said Elite players are required to undergo swab testing and quarantine for seven days once they test negative and show no symptoms.
"One, hindi pa pinapayagan ng PBA. Two, may go-signal pero wala pang letter kasi ginagawa pa ng (Inter-Agency) Task Force. 'Yun ang sinasabi ko," Marcial explained to TV5 correspondent Lyn Olavario.
Sy bared on TV5's Sports Page on Monday that Blackwater had already begun working out over the weekend, but Marcial clarified that teams are still not allowed to hold closed-door practices.
The league will also investigate the remarks made by team owner Dioceldo Sy about selling the franchise. Sy said on Wednesday that he is "open to talk with any company interested to join the PBA" and that he is "not interested with the PBA at this point in time."
Though he declined to give additional details, Marcial said the Commissioner's Office will forward to the Board of Governors the results of its investigation on Sy's statements about selling the Blackwater franchise.
"Regarding sa selling the franchise, seryoso at mabigat 'yung mga sinabi ni Mr. Dioceldo kaya papa-imbestigahan ko. Pagkatapos ng imbestigasyon, papadala ko agad sa board yung findings at recommendations ko," he added.
Marcial said Sy has yet to submit a letter of intent to the PBA about putting the team up for sale.
