The Dallas Mavericks made the acquisition of guards Darren Collison and Dahntay Jones official Thursday evening.

They come over via a sign-and-trade completed Wednesday with the Indiana Pacers that sent backup center Ian Mahinmi to the Pacers, who will pay the big man $16 million over the next four years.

Collison, 24, is due $2.3 million next season, the last final year of his rookie contract. He is expected to take over as the team's starting point guard. The defensive-minded Jones, 31, is owed $2.9 million next season and is also entering the final year of his deal.

“We are thrilled to add these two players to our roster,” president of basketball operations Donnie Nelson said in the team release. “Darren is a young, explosive point guard with tremendous upside. He has proven that he can lead a playoff team and we are excited about his potential. Dahntay is a rugged veteran who will play the kind of tough defense that will fit perfectly in coach (Rick) Carlisle’s system."
