All three are in the country to watch the EuroLeague Final Four.
King had said he was going to Turkey last week to do some scouting and to meet with Bojan Bogdanovic, one of the team's second-round picks last season. The Nets hold Bogdanovic's rights. The 23-year-old swingman is playing for Fenerbahce in the Turkish League -- though his team already has been eliminated -- and has an NBA out in his contract in 2013.
Williams has reiterated his intentions to opt out of his contract and become a free agent. He played for Besiktas in the Turkish League during the lockout.
The meeting provides Prokhorov and King another opportunity to express their desire to keep the All-Star in a Nets uniform long-term. When Williams opts out, he can re-sign with Brooklyn for five years and $109 million -- or one year and $28 million more than any other team based on the new rules of the CBA.
A report over a week ago said the Nets had come to terms on a verbal agreement on a three-year deal with Kirilenko, but league sources denied the report and said nothing was imminent. Still, Kirilenko is the type of versatile big man the Nets might covet, and given his relationship with fellow Russian Prokhorov, it's something to keep an eye on going forward.
The Nets only have one forward under contract -- Jordan Williams.
Deron Williams tweeted a photo Friday of Kirilenko shooting a free throw during Friday's game against Panathinaikos, and both King and Williams have tweeted similar photos of their views in Istanbul.
The meeting was first reported by the New York Post.
