He did taste action in the victorious 2012 campaign, completing just one group stage game before fracturing his fibula against Indonesia in the second match.
The hard-working forward fractured his skull and cheekbone after he was kicked in the head by ATM's Amiridzwan Taj while featuring for LionsXII last year.
He returned to action in March this year with his new club Warriors, wearing protective headgear similar to that used by Chelsea goalkeeper Petr Cech.
The 29-year-old LionsXII forward fractured his cheekbone earlier this season after being elbowed by Felda United midfielder Ahmad Syamim Yahya. He was ruled out for about two months.
In 2010, he tore one of his leg muscles while playing for Persiba Balikpapan in Indonesia and was out of action for about eight months.
