We have obtained Spitzer Space Telescope MIPS observations of 40 F- and G-type common proper motion members of the Scorpius-Centaurus OB association with ages between 5 and 20 Myr at 24 and 70 µm. We report the detection of 14 objects that possess 24 µm fluxes ≥30% larger than their predicted photospheres, tentatively corresponding to a disk fraction of ≥35%, including seven objects that also possess 70 µm excesses ≥100 times larger than their predicted photospheres. The 24 µm plus 70 µm excess sources possess high fractional infrared luminosities, L_IR/L_*=7x10^–4 to 3x10^–3; either they possess optically thin, dusty β Pictoris-like disks or compact, opaque HD 98800-like disks.
