Hibernian faced Hearts for the 40th time in the Scottish Cup, with both teams aiming to make it to round five.
Robbie Neilson, who took in the game from the stands following his red card midweek, saw his side come into the game as favourites; the Jambos sitting clear in third in the table and recording a convincing 3-0 win in the last Edinburgh derby earlier in the month.
It was Hibs who had the first sight of goal when veteran winger Aiden McGeady worked space, before finding Josh Campbell whose clever flick came back off the post.
Despite a shaky start, Hearts soon flexed their muscles and silenced the home crowd with an early opener. Robert Snodgrass’ delicious free kick was headed away to the edge of the box where the ball broke to Josh Ginnelly who rifled a low volley beyond David Marshall.
Hibs were handing a debut to Australian midfielder James Jeggo, announced less than 24 hours before kick off, in a bid to add an experienced midfield anchor. The 30-year-old appeared to struggle with the early pace however and picked up a needless caution with just over 20 minutes gone.
Josh Campbell should’ve equalised for Lee Johnson’s men before half time. Aiden McGeady continued to cause problems for the Jambos, with the winger delivering a clipped ball into the back post where Campbell could only direct his header wide.
