Greg Slaughter will take the spot of the injured Roger Pogoy, Gilas coach Tim Cone announced after their practice on Monday.
"It's gonna be announced in the manager's meeting tomorrow (Tuesday) at 2 p.m. We have a medical certificate for Pogoy and Greg will replace him in the lineup," Cone said.
Pogoy, who hurt his back late in the 2019 PBA Governors' Cup quarterfinal match against defending champion Magnolia last week, was diagnosed with a bulging disc.
Slaughter showed quickness running up and down the court during Gilas' brief practice.
"He's playing really well. His thumb is fully healed and I think a seven-footer in the Gilas program is a must because you're gonna try to develop those guys, just like you need a Kai Sotto eventually," said Cone. "Those guys are rare. They don't come around all the time."
Cone said if not for the injured thumb, Slaughter would have easily made the original Gilas lineup.
"I think the only reason we didn't include him (Slaughter) in the original 12 in the first place was because of his thumb. We're not sure how severe (the injure was on) his thumb, and how well was he's coming back," explained Cone.
Slaughter managed to play in Ginebra's 100-97 quarterfinal victory over San Miguel Beer last week, tallying 5 points and 4 rebounds in 20 minutes.
"He played in our last game against San Miguel hurt. He didn't have much feel and he had brace on his thumb," said Cone. "The idea was to defend June Mar and you can do that without your thumb."
Slaughter completes the Gilas final 12 cast that includes Ginebra teammates LA Tenorio and Japeth Aguilar and Stanley Pringle, Fajardo, Marcio Lassiter and Chris Ross of SMB, TNT's Troy Rosario, Alaska forward Vic Manuel, NorthPort's Christian Standhardinger, Phoenix's Matthew Wright and NLEX guard Kiefer Ravena.
Gilas will have one last practice on Tuesday before making its much-awaited SEA Games debut on Wednesday against Singapore at the Mall of Asia Arena.
