EuroCup Challenge hopefuls Ural Great Perm have bolstered their ranks by signing American forward Ellis Myles.
The 24-year-old played 37 games in the NCAA with Louisville last season and averaged 10.4 points and 9.2 rebounds a game.
Myles began this season with Italian club Viola Reggio Calabria and played 12 games for them with 15.9 points and 10.2 rebounds.
Ural Great are in the semi-finals of the EuroCup Challenge where they will play Greek side Olympia Larissa on February 23.
Ural Great's Russian rivals CSKA Moscow have signed 27-year-old Belgian centre Thomas Van den Schpigel until the end of this season from Italian side VidiVici Virtus Bologna.
Van den Schpigel, who signed a contract with CSKA on Friday after passing a medical, will help the Moscow club cover the loss of injured Australian David Andersen.
Van den Schpigel told Sport Express: "It's prestigious for any player to play for a club like CSKA. I'll try to show my best during the next four months.
"I know that CSKA have serious goals in every competition they play, and I like to win."
With regards to his lack of action with Virtus in recent months, Van den Schpigel added: "I missed most of this season and the main reason was an ankle injury that I got in November.
"I missed two weeks due to that but it was almost impossible to get back to the main squad."
Meanwhile, Sergei Kuschenko has been appointed CSKA Moscow president following last week's board meeting, with Yuri Yurkov taking over as the new chief executive.
