The Minnesota Timberwolves have signed Lazar Hayward.

Hayward, who played collegiately at Marquette, has appeared in 69 NBA regular-season games with Minnesota and Oklahoma City, posting averages of 2.9 points and 1.3 rebounds in 8.2 minutes per game.

Even with the signing of Hayward, the Timberwolves will continue to look to bolster their wing depth.

The Washington Wizards have officially signed guards Shelvin Mack and Garrett Temple, the team announced on Wednesday.

Mack was originally selected by Washington with the 34th overall pick in the 2011 NBA Draft. In 11 games this season with the Maine Red Claws of the NBA D-League, he has averaged 19.7 points and a D-League best 7.5 assists in 40.7 minutes per contest.

Temple was undrafted out of LSU in 2009. In nine games this season with the Reno Bighorns of the D-League, he has averaged 14.7 points, 4.9 rebounds and 5.8 assists in 36 minutes per contest.

The Boston Celtics have signed Jarvis Varnado.

Boston has been thin in the frontcourt.

Varnado was the 41st overall pick in the 2010 NBA Draft by the Miami Heat, but never played a game with the franchise.

The Charlotte Bobcats have signed forward Jeff Adrien while waiving guard Cory Higgins, the team announced on Sunday.

Adrien joins the Bobcats from the Rio Grande Valley Vipers of the NBA D-League, where he averaged 17.6 points on .563 shooting, 11.2 rebounds, 1.2 assists and 1.2 blocks in five games played so far this season.

Higgins was in his second season with the Bobcats, with career averages of 3.7 points, 0.9 rebounds and 0.9 assists in 10.3 minutes in 44 games played.
