Ante Tomic remains undecided about his NBA plans.

Tomic was drafted by the Utah Jazz in 2008 and they would like to bring him over to help their frontcourt rotation.

"It’s neither yes nor no," Tomic told the Spanish publication Gigantes when asked whether he plans to leave Barcelona for the NBA and the Utah Jazz. "It’s difficult to summarize. Sometimes I see myself there and others no. I still have time to think it over."

Tomic has played for Barcelona since 2012 and is already 28 years old.

Andrei Kirilenko has decided to retire from professional basketball.

Kirilenko wasn't invited to join Russia's squad for EuroBasket 2015.

Kirilenko joined the Utah Jazz in 2001 and was an All-Star in 2004. Kirilenko played for CSKA during the lockout and then returned to the NBA to play for the Minnesota Timberwolves and Brooklyn Nets. Kirilenko was traded to the Philadelphia 76ers this season and he never reported to the team.
