The Ivorian midfielder's contract at Manchester City expires at the end of June, making him a free agent this summer.
Although Toure's CV boasts numerous trophy wins and individual accolades, Hurst has suggested that the 35-year-old is controversial and "past his best".
"When I see them linked with Toure I just think that's completely and utterly off the wall," the England World Cup winner told the Daily Star. "I absolutely cannot believe as a club we're looking at him.
"There comes a time when a player is past his best and we shouldn't be buying cast-offs from other teams."
Toure made 316 appearances for Man City, scoring 79 goals and registering 50 assists.
