Brian,
Man I’m sorry to hear this. I would take it easy and get that knee healed up first. Racing is a hobby; your job is your lively hood. If you do decide to race though, I would have no problem staging next to you. Do what you are comfortable with. If you decide to wait until the knee is healed, at least come out and be a spectator once and a while. Take care and have a fast recovery.
