The Houston Rockets signed Joey Dorsey to a two-year, $2 million contract to replace Omer Aski as center Dwight Howard's backup, according to Yahoo! Sports' Adrian Wojnarowski.

The Rockets also reached an agreement on a one-year contract with former Milwaukee Bucks forward Jeff Adrien for the veteran minimum, the Houston Chronicle reported Tuesday.

The Rockets have focused on rebuilding their depth after parting ways with Asik, Chandler Parsons and Jeremy Lin this offseason. Dorsey, 30, has not played in the NBA since 2011. In parts of three NBA seasons, he owns modest averages of 2.6 points and 3.8 rebounds in 61 career games.

Dorsey was the No. 33 overall pick out of Memphis in 2008, and landed with the Rockets in a draft-night deal. He spent less than two seasons with Houston before spending time with the Sacramento Kings and Toronto Raptors.

Only once has Dorsey averaged double-digits in minutes played, and he is a 46.8 percent career free throw shooter.

He signed with Spanish ACB League club Caja Laboral in September 2011, only to have his contract terminated four months later and signed on with Greek Basket League powerhouse club Olympiacos until the end of the season.

Dorsey re-signed with Olympiacos for two years in September 2012, but was released two months later after publicly criticizing the team. He landed with Turkish Basketball League club Royal Hali Gaziantep until the end of the season and ultimately signed with Spanish team FC Barcelona in July 2013.

Adrien was traded to the Bucks from Charlotte in February and proved productive in Milwaukee during the remainder of the 2013-14 season, averaging 10.9 points and 7.8 rebounds per game. In 53 games between the two teams last season, he averaged 6.8 points and 5.8 rebounds.

The 28-year-old Adrien began his NBA career with the Golden State Warriors in 2010 and then played in eight games for the Rockets in 2011-12 before going to Charlotte. He has career averages of 4.8 points and 4.3 rebounds per game.
