The 6-foot-6 Fil-Am behemoth suffered calf and toe injuries in a bar fight, according to reports. The STAR tried to make calls but failed to get confirmation from the Ginebra team.
Sources, however, said Menk has been absent from the Ginebra training since Wednesday.
The Kings are bracing up for their coming Final Four showdown with either the Talk n Text Phone Pals or the Purefoods Chunkee Giants.
Ginebra topped the classification round with a 15-3 win-loss card with Menk averaging 14.1 points, 8.7 rebounds, 2.6 assists for the team.
Menk is second to Mark Caguioa (22.7 points a game) in scoring and also second in rebounding behind Rudy Hatfield (11.8 per game).
The 2005 MVP winner ranks No. 5 in offensive rebounds with 3.4 a game.
