Worcester Wolves have added points guard Marek Klassen and forwards Deondre McWhorter and Trevor Setty to their roster for next season.
Klassen averaged 17 points, and eight assists, in the British Basketball League for Leeds Force last season.
Setty returns to the BBL after previous stints with Plymouth and Surrey.
McWhorter, who is 6ft 9in, averaged 18 points, and 10 rebounds, for Georgetown College in America in 2015-16, when he was named national player of the year.
"We really struggled at points guard last season and Marek is very intelligent and he does it all - he's the guy we've brought in to cement the team," head coach Paul James told BBC Hereford and Worcester.
"Trevor can really shoot the lights out and is another player who really wants to win and if he clicks with Klassen, he could be one of the best players in the league.
"Deondre is coming straight from college and has a great skill-set. It's his first professional contract and it's a great opportunity for him."
James also confirmed the club will be losing American forward Perris Blackwell while another forward, Pavol Losonsky, is to join a club in France.
