Joey Votto is a human, even if his numbers suggest otherwise. Unfortunately, it's still pretty hard to predict how long humans will take to recover from injuries. After a setback earlier this month, Joey is now on track to return Saturday, September 1st (no roster move will be necessary then) - though that's subject to change. Votto originally injured his knee on June 29th, then re-injured (or maybe further injured it) on July 16 and had surgery the next day. His original ETA was 3-4 weeks, but if he returns Friday, it will have been just over 6 weeks since he's played in the majors. That's not too surprising, given the history of similar players with similar injuries. And also the history of teams generally playing low-ball with injury estimates.
