Alternatively, I would include it along with your two best Employer recs. Some schools prefer that you have at least one Academic rec, so I would include it unless it was really bland. You graduated a few years back, but not long enough that you should have serious trouble getting a college rec, so its absence from your file would probably be noted
I graduated in 2001, and got one of my old profs to do it. I ensured he remembered me and got some substance for the rec by meeting with him and giving him a copy of my transcript and a copy of my professional resume. I recommend you try the same.
