New Zealand Warriors chief executive Cameron George says the NRL club would be "mad" not to try to sign Sonny Bill Williams.

Williams could be available on a short-term deal after Toronto Wolfpack withdrew from the rest of the Super League season on Monday due to the financial impact of the coronavirus pandemic.

Former New Zealand centre Williams signed a two-year deal with Toronto last November and the Wolfpack are planning to return to action next year.

George revealed the Warriors will ask about the cross-code star's availability for the remainder of the NRL campaign.

"We're in a position where obviously we're going to require players and if Sonny Bill Williams becomes available, of course, we're going to look at how it could happen," he told NRL.com.

"We'll reach out for sure to try and understand the situation, we're already looking for loan players so imagine if it came off.

"The stars would have to be aligned, and I don't know if and when Sonny could even get to Australia. But we'd be mad not to ask the question."

Sydney Roosters have also been linked with a move for the 34-year-old Williams.
