LOS ANGELES (thefutoncritic.com) -- FOX is sending "Sons of Tucson" to the leadoff spot on Sunday nights.

The show's swan song will shift to 7:00/6:00c on June 27, network sources have confirmed to the site exclusively.

The series will take over for "'Til Death," which wraps its run this coming weekend.

"Tucson" had originally been set to continue in the 7:30/6:30c half-hour, preceded by "American Dad" repeats.

The two will instead swap while the rest of FOX's Sunday lineup will remain as previously announced.
