On December 6, 2017, it was reported that Sinclair and Fox were working on a deal that would see its Fox affiliates renew their affiliation agreement in exchange for Sinclair selling some of its Fox affiliates directly to Fox Television Stations. The deal would see between six and ten Fox affiliates owned by Sinclair and Tribune (all in markets with an NFL team) become Fox owned-and-operated stations. It is not known if WUTV will be one of the stations sold, although the stations being sold to Fox are expected to be from Tribune Media (notably KCPQ in Seattle, where Sinclair already owns KOMO-TV), many of which were previously owned by Fox. A sale to Fox would make WUTV Buffalo's first Big Four network O&O since WBUF-TV (channel 17, now PBS member WNED-TV), which was owned by NBC from 1955 until its sign-off in 1958. On May 9, 2018, Sinclair announced that seven Fox affiliates would be sold to FTS, but WUTV was not included and an affiliation renewal was announced for that station instead, keeping WUTV with Sinclair.

On May 23, 1994, Fox network parent News Corporation and New World Communications signed a long-term affiliation agreement in which thirteen television stations affiliated with either CBS, ABC or NBC (five that New World had already owned, and eight that the company was in the process of acquiring through separate deals with Great American Communications and Argyle Television Holdings) would switch to Fox. WJW-TV (channel 8) – which had served as Cleveland's CBS affiliate since March 1955 – was among the New World stations slated to join Fox as part of the group affiliation deal once individual contracts with each of the stations' existing affiliated networks expired. Fox wanted to upgrade affiliates in certain markets in response to its acquisition of the National Football Conference's broadcast television rights, which had been carried by CBS for the previous 38 years, starting with the 1994 NFL season.
