India's strong start in the Boxing Day Test at the MCG crumbled within 30 minutes, slipping from 153/2 to 159/5 due to a mix-up between Yashasvi Jaiswal and Virat Kohli and poor decisions on Day 2. Australia now holds a 310-run lead. Despite Jaiswal and Kohli's earlier efforts, India's concentration lapses have put them in a difficult position.
