of reports on Twitter that the Brooklyn Nets set Wednesday as a deadline for their trade talks with the Orlando Magic over All-Star center Dwight Howard.

Wojnarowski adds on Twitter that Brooklyn is prepared to forego their Howard pursuit to keep Lopez. ------------------------------------ Brooklyn's fully guaranteed the first 4 years, $58M of a max deal offer for Brook Lopez, sources tell Y! Sides still discussing 5th year. To keep alive chances to get Howard, Billy King can't let Lopez sign sheet. Nor can he let him walk if Nets don't get DH. Has to pay Lopez.
