Joe Johnson underwent an MRI in Atlanta on Tuesday, and he was diagnosed with left knee tendinitis. As previously announced, he’ll miss the Hawks’ next two games.

In addition, Johnson won’t participate in this weekend’s All-Star game and activities in Orlando. He will be re-evaluated prior to Atlanta’s first game after the All-Star break

Gary Washburn of the Boston Globe is reporting that Rajon Rondo will replace Johnson on the Eastern Conference All-Star team.

Joe Johnson explained why the Hawks have a motivation problem and play with a lack of energy at times.

"When I look at our team, we are a very talented team, but I [don't know] whether guys know their roles or not," Johnson said. "We know the right thing to do. A lot of times we don't come out and do it. I just think we should all have one agenda, one goal and that is winning the basketball game. Not who scores what, who does what. I think we are too self conscious about [who is] scoring and the little things that really don't matter. For us to win the game we have to put all of that to the side and help one another on both ends of the floor. If we don't do that, we are going to continue to struggle to win games. I think we have to put a lot into perspective about how good we want to be as a team or what direction we are headed in or what are our goals. Right now I'm not sure if everyone has that one common goal – and that is winning.

"We've had spurts where we've played great together. The ball movement has been great. We've had times when we haven't been so great. Times we haven't been so great, we have struggled as a team. I know it's noticeable. I think we just have to start getting the ball into the right people's hands who make plays, who score the basketball and make others better. That's it."

Marvin Williams continues to be an ancillary part of Atlanta's offense and sources say he would like a trade.

Williams is averaging just 9.6 points per game this season and would like to find a situation where his usage increases.

The Atlanta Hawks today signed center Erick Dampier to a second 10-day contract.

Dampier has appeared in four games for the Hawks this season, after signing his first 10-day contract on February 9, averaging 2.5 rpg, 0.3 apg, 0.3 spg and 0.3 bpg in 6.5 mpg.

Tracy McGrady is frustrated with his disappearing reserve role.

“I’m tired of this [bleep],” McGrady said after logging just 4:39 during the 97-77 loss to the Blazers late Saturday. “You can put that in the paper, I don’t give a [bleep].”

McGrady said coach Larry Drew hasn’t offered him an explanation when he doesn’t play him many minutes.

“If you don’t feel I can help, come tell me that,” McGrady said. “He ain’t told me nothing. I just want to help these guys win, man, which I know I can. But, damn, four minutes?”

McGrady is eligible for a trade on March 1, but indicated he would prefer to remain with the Hawks.

“Hopefully, I’m here,” he said. “I like it here. I like the guys. That’s what I love most about it. I like the guys in this locker room. But at the same time, I still can play. No doubt in my mind.”

Kyrylo Fesenko is ready to return from a torn meniscus in his left knee.

"He's fine now; he's ready to go," said Stu Lash, Fesenko's agent.

The Bucks, Bulls, Heat, and Hawks are showing interest in Fesenko, who spent last season as a backup center for the Jazz.

Milwaukee is trying to set up a meeting with Fesenko next week.

The NBA announced the field for the 2012 Three-Point Contest on Wednesday.

Ryan Anderson (Orlando), Mario Chalmers and James Jones (Miami), Joe Johnson (Atlanta), Anthony Morrow (New Jersey) and Kevin Love (Minnesota) comprise this season's field.

Josh Smith was left off the All-Star roster by the Eastern Conference coaches, who picked the reserves earlier this week.

 “You’ve got to factor in there is a lot of politics involved in the All-Star selection,” Smith said Friday. “Once you get that it’s really about politics, then nothing really surprises you. I call it ‘Nothing But Associates,’ NBA. It’s all who you know.”

Andre Iguodala, Paul Pierce, and Luol Deng were chosen as reserve forwards.

Smith said “I guess I don’t know the right people” and didn’t have people lobbying on his behalf.

“I can’t really point a finger and blame anybody because, at the end of the day, when you leave it up to certain people that still have ties to their agents, [and] players in this game today probably [are] just putting in a bid over the phone, or however they do it,” he said. “You have to factor that in.”

The NBA announced the reserves for the 2012 All-Star Game on Thursday.

Joining LeBron James, Dwight Howard, Derrick Rose, Dwyane Wade and Carmelo Anthony on the Eastern Conference team are Chris Bosh, Luol Deng, Roy Hibbert, Andre Iguodala, Paul Pierce, Joe Johnson and Deron Williams.

Kobe Bryant, Chris Paul, Blake Griffin, Andrew Bynum and Kevin Durant will have LaMarcus Aldridge, Marc Gasol, Kevin Love, Steve Nash, Dirk Nowitzki, Tony Parker and Russell Westbrook on their Western Conference team.

The Atlanta Hawks have signed 15-year veteran center Erick Dampier to a 10-day contract.

Selected 10th overall by Indiana in the 1996 NBA Draft, Dampier has played in 972 regular season games and 57 playoff contests with Indiana, Golden State, Dallas and Miami. He appeared in 51 games last season for the Heat, averaging 2.5 ppg, 3.5 rpg and 0.9 bpg (.584 FG%, .545 FT%).
