About a week. That’s how long Tim Tszyu estimated that he stayed away from the gym in Australia after Bakhram Murtazaliev brutalized him 5½ months ago. The prideful Sydney native couldn’t stay away from at least light training any longer than that, though his body obviously could’ve used more rest, because he wanted to begin the process of correcting countless mental and physical mistakes that led to him getting dropped four times during a third-round, technical-knockout defeat.
