New Lakers center Timofey Mozgov injured his groin while playing for the Russian national team in an international friendly against Ukraine on Friday.
After undergoing an MRI on Saturday, Mozgov will miss Russia's next two games at its international tournament in Tbilisi, Georgia, and be re-evaluated sometime mid-next week, per Lakers spokesman John Black.
The Leningrad native has a decorated career representing his home country, including winning a bronze medal at the 2012 London Olympics where he averaged 10.0 points. He played professionally in Russia for six years prior to the NBA and also helped his national team to bronze at the 2011 FIBA European Championship.
Mozgov signed with the Lakers on July 8 after spending his first six seasons in New York, Denver and Cleveland. He averaged 6.3 points and 4.4 rebounds while shooting 56.5 percent last year during the Cavaliers' championship campaign.
