Pacers CEO Donnie Walsh said Monday he expects some type of "breakthrough" this week in negotiations for a sign-and-trade deal for Al Harrington, who spent his first six seasons in Indiana.

"It's at that point where it has to get done or it doesn't get done," Walsh said.

Walsh talked Monday with team owners Mel and Herb Simon, and they'll talk again today.

If a deal is reached, Harrington will sign a six-year, $57 million deal with Atlanta, then be shipped to the Pacers along with center John Edwards. The Pacers will give Atlanta their $7.5 million trade exception and a future first-round draft pick.

The Pacers have been the front-runner to acquire Harrington, but talks slowed because he switched agents.

"We're back and dealing with it now," Walsh said. "We expect some type of breakthrough this week -- at least that's what I'm hoping."

"We're just waiting for them to tell us what they want to do," Hawks general manager Billy Knight told the Atlanta Journal-Constitution.
