More emails have come to light which could put the Sonics' move to Oklahoma City in jeopardy, or at least slow the process, Gregg Bell from the Associated Press is reporting.

The new emails show that the NBA was concerned last summer that Sonics owners may be breaching their contractual promise of good-faith efforts to find a new arena in Seattle.

In court documents provided Thursday by attorneys representing the city, Bennett stated in an e-mail to Sonics co-owner Aubrey McClendon last Aug. 13 that the NBA was looking into issues "relative to certain documents that we signed at closing that may have been breached."

Bennett wrote that president of league and basketball operations Joel Litvin was looking into the possible breach.
