It looks like negotiations between the Philadelphia 76ers and restricted free agent Samuel Dalembert took a turn for the worse on Monday according to ESPN correspondant Chad Ford.

The two sides have been negotiating for three weeks but have been unable to come to terms on a new contract. Over the course of the last week, there has been a great level of frustration on both sides.

On Monday, Dalembert's agent, Marc Cornstein, said Dalembert had scheduled a visit in Atlanta with the Hawks on Monday, July 25.

But Sixers general manager Billy King said the Sixers are still determined to match any offer for Dalembert.

"Sam will be in Philly whether it is at our number or a number that someone else sets," King wrote in an email to ESPN. "HE WILL BE IN PHILADELPHIA ONE WAY OR ANOTHER."

When asked about King's stance, Cornstein acted surprised.

"We're getting mixed messages," Cornstein said. "They've drawn a line in the sand with Sammy's contract with what they're willing to pay. Yet he's telling you they'll match any offer. There is a huge gap between Philadelphia's offer and what other teams under the salary cap can offer."

The Hawks are roughly $23 million under the cap -- enough money to make a run at two top-tier free agents. The Hawks are believed to have earmarked roughly half that amount for free agent Joe Johnson. They want to add a center with the rest of it. Restricted free agent Eddy Curry visited the Hawks last week, but left Atlanta without a contract offer.
