FORT COLLINS — Colorado State collected its first win in a Rocky Mountain Showdown tuneup, but the cost might have lasting effects on the Rams’ season. CSU defeated Northern Colorado, 38-17, in a Saturday performance at Canvas Stadium that will draw mixed reviews in its own right. But the biggest story moving forward could be the availability of star wide receiver Tory Horton for the showdown next weekend with rival Colorado in FoCo. The all-conference pass catcher left Saturday night’s game in the third quarter and did not return.
