Bad injectors - running rich?

Could bad injectors cause a rich condition (to the point of the cat glowing red while idling)?
According to my mechanic-the car starts fine, but then after it warms up, it starts running rough, and eventually the cat issue happens.

The injectors are new/refurbed, but they are oem aftermarket so not sure if I trust them.

Much more likely that the CAT is clogged up
