After a week of talks, the Los Angeles Lakers and Cleveland Cavaliers could not find common ground on a trade involving Pau Gasol and Andrew Bynum by Sunday night, sources told ESPN.com.

While there was disappointment a resolution was not reached by Sunday night, there is an expectation that talks between the teams would continue into Monday, sources said.

Both sides were interested in getting something done before the end of the weekend, but they could not get traction. The Lakers leave Monday for a road trip to Texas and the Cavs wanted to be able to process physicals of any new players before Tuesday's deadline for Bynum's contract to be guaranteed.

Though the discussions have been varied and both sides considered numerous possibilities, the central issue never wavered, sources said.

The Lakers wanted more than just salary savings that trading for Bynum and waiving him would bring, primarily a young player or valuable draft pick. Trading for and cutting Bynum had the potential to save the Lakers more than $20 million in salary and luxury taxes. The Cavs, who stood to add millions to their own payroll with the deal, have resisted meeting the price because Gasol will be a free agent at the end of the season.

The Cavs are considering two other possible deals, sources said. One is to trade Bynum to the Utah Jazz for veteran forward Richard Jefferson.
