If your weight room is available to you in the mornings, I would go in and do a brief workout along the lines of Waxman's advice. You will be fresher in the morning to get some good work in, and will have most of the day to recover prior to afternoon practice. Just make sure your recovery nutrition is in order, or you'll still feel drained at practice.
This is from personal experience training MMA, I found I made better gains in strength(and size when that was my focus) by splitting my strength/conditioning work from my skill work. Since wrestling practice is a form of conditioning, just concentrate on lifting for strength, and I wouldn't worry too much about energy system work during the season, you are probably getting plenty of that from practice.
