The New York Knicks have turned to restricted free agency for centre depth.

The Mavericks have until Monday to match the offer.

Cisse, 23, is coming off a rookie season with the Mavericks in which he appeared in 38 games, averaging 4.5 points and 5.7 rebounds per contest.

New York lost centre Mitchell Robinson to the Boston Celtics in free agency, though it has since added veteran Andre Drummond to its frontcourt.
