The 37 year old Powar had briefly donned national colours in the early and middle part of last decade, playing 2 Tests and 31 ODIs.
Powar took six wickets in two Tests -- both against Bangladesh while he was relatively better in shorter format with his fast off breaks yielding 34 scalps.
But he was a stalwart for Mumbai as his 442 first class wickets are a testimony.
He formed a potent spin attack with Sairaj Bahutule during those years when Mumbai won multiple Ranji Trophies. Poor fitness and weight problems were impediments towards finding a permanent slot in the team.
"I have tried to be an honest servant of the game that I love most. I would like to be associated with the game in any capacity," Powar, who will be playing in Masters Champions League, said.
