There are no plans to place a team in Philadelphia, but three Pennsylvania markets are under consideration - Wilkes-Barre, Hershey and Reading.
"We didn't want to impede on the Wings," the source said.
Other likely destinations for the league are Orlando, Charlotte, Richmond and Newark, N.J., although the source said negotiations continue on leases with arenas. Each team will be independently owned with local ownership in its home market.
The source said the league has a goal attendance of 2,000 to 3,000 per game, although ideally it would be looking at larger crowds in bigger markets.
Player salaries will be on par with Major League Lacrosse, the outdoor league that plays in the summer, at about $500 to $1,000 per game. Teams will be made up almost exclusively of American players. More than 80 percent of the players in the NLL are Canadian. Players Peter Vlahakis, Stephen Berger and Steve Panarelli are scheduled to attend the news conference.
The league also will name Phil Evans as its commissioner. Evans spent 5 years as the president of the NBA Developmental League and also worked for the Continental Basketball Association for 3 years.
