The Toronto Raptors are showing significant resistance to trading point guard Kyle Lowry and appear determined to keep him as they pursue a postseason berth, league sources told Yahoo Sports.

"We've heard it from [Toronto] that he won't be moved," a rival front office executive told Yahoo Sports.

While there are never absolutes – especially if a team makes an unexpectedly rich offer – Toronto officials and sources close to Lowry have emphasized lately that Lowry appears destined to finish the season with the Atlantic Division-leading Raptors.

The NBA's trade deadline is February 20.

Lowry has had the most productive season of his career, carrying a strong leadership load and averaging 16.7 points and 7.5 assists. Toronto risks losing Lowry without compensation to free agency this summer.

Lowry, 27, could demand a free-agent deal in the four-year, $45-million range based upon his revival with the Raptors.
