WPNT
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. Originally speculated that WPGH-TV may be sold to Fox while Sinclair retained WPNT, it was later reported that WPNT might be included in the deal as well in order to keep the two stations together, which would make WPNT a MyNetworkTV owned-and-operated station. On May 9, 2018, Sinclair announced that seven Fox affiliates would be sold to FTS, but WPGH-TV was not included and an affiliation renewal was announced for that station instead, keeping WPGH-TV and WPNT with Sinclair.
KSWB-TV
On December 15, 2017, it was speculated that Sinclair would resell KSWB-TV to Fox Television Stations upon approval of the Tribune deal. On April 24, 2018, Sinclair announced that KSWB-TV would be one of 23 stations sold to obtain approval for the merger, though it was one of seven stations for which a buyer was not disclosed. On May 9, 2018, it was officially announced that Fox Television Stations would buy KSWB-TV, as part of a $910-million deal that also involved six other Tribune-owned stations (Fox affiliates KTXL, KCPQ/Seattle, KDVR/Denver, WJW/Cleveland and KSTU/Salt Lake City, and CW affiliate WSFL-TV/Miami). If the sale is approved, it would make KSWB-TV (and sister station KTXL) a Fox owned-and-operated station and sister to KTVU in Oakland/San Francisco and KTTV in Los Angeles. It would also be the third O&O station in San Diego (behind NBC O&O KNSD and Telemundo O&O KUAN-LD).
