Excruciating warmup with lots of running jumping pushups. Shadowboxing. Then everyone just broke off in pairs and practiced combos on eachother. I rolled the first round and had a pretty good one with a fighter that's better than me but smaller. I stayed between side control and half guard for most of the round. Unfortunately I also irritated my old knee injury. Nothing terrible, just a bit of pain. This is shitty timing because I really wanted/needed to get some more sparring at the pro gym. Will improvise and make do with something else instead.
