"On the first day that NBA front office executives were allowed to resume communication with player agents, Thunder general manager Sam Presti began preliminary discussions with Russell Westbrook's agents on a contact extension.

Westbrook is now eligible to receive an extension to his rookie scale contract after playing three seasons. A potential deal cannot be signed until Dec. 9, when the free-agent signing period officially begins. But a new deal would not take effect until the 2012-13 season.

"We made calls to all kinds of (representatives of) free agents, as well as our own players to touch base and talk about whatever issues we need to cover with each player respectively," Presti said Wednesday night at a Thunder fit clinic at the Salvation Army Boys and Girls Club in southeast Oklahoma City."
