Toughest part for Perriman going forward will be mental, not physical. Athletes like former UFC champ Tito Ortiz, former No. 1 contender Jon Fitch have had partial ACL tears, healed in six weeks or so and returned to form. UFC fighter Heather Jo Clark twice fought with a complete tear of her ACL -- winning once and staying competitive in the other. Biggest challenge for Perriman, especially since he missed all of last year, will be trusting completely in the knee and not holding back on the field. If I were him, I'd be doing yoga five times a week and start my warm-ups at least an hour before practice.
