Ivan Johnson’s contract with the Dallas Mavericks will be for two seasons, with partial guarantees, league sources told RealGM.

The Mavericks announced the signing on Tuesday.

Johnson played for the Mavericks’ summer league entry in Las Vegas, averaging 7.8 points, 3.8 rebounds, one steal and 20.8 minutes per game.

Johnson spent the 2013-14 season with the Zhejiang in the Chinese Basketball Association.

Johnson, 30, had two productive seasons with the Atlanta Hawks in 2011-12 and 2012-13 – scoring 6.5 points and grabbing 3.9 rebounds per contest in 125 total NBA games. The 6-foot-8 forward worked himself back into the league through workouts late last season and into the summer.

Darius Miller re-signed with the New Orleans Pelicans on Friday.

Originally drafted by New Orleans with the 46th overall pick in the 2012 NBA Draft, the University of Kentucky product averaged 4.4 points and 1.2 rebounds in 16.1 minutes per game during the 2013-14 season.

Miller has appeared in 97 career games (nine starts) for the Pelicans over the last two seasons, averaging 3.3 points and 1.3 rebounds in 14.6 minutes per game.

Eric Griffin’s contract with the Dallas Mavericks is a three-year, non-guaranteed deal, league sources told RealGM.

The Mavericks announced the free agent signing of Griffin on Friday.

Griffin is averaging 9.8 points, 2.8 rebounds and two blocks for the Mavericks’ summer league team this month, and he’s a high-level athlete and an increasingly skilled forward. At 6-foot-8, Griffin had arguably the best dunk of summer league: a one-handed slam over Shane Larkin.

Griffin had gone to training camp with the Miami Heat last season and was a final roster cut. He then played in Puerto Rico and Venezuela.

Griffin, 24, averaged 15.7 points and 8.7 rebounds in his senior season at Campbell University.
