Essex 457-8dec v Durham 333 & 63-4
Ollie Robinson and Colin Ackermann return to the middle with Durham trailing by 61 runs and 65 overs remaining in the day.
Can't take your eye off this one for a minute.
Essex are a bowler short with no Shane Snater but have dealt with the workload manfully thus far, but Doug Bracewell has also been off for some treatment this morning.
Simon Harmer takes the first over but Jamie Porter is refreshed and will surely get a burst at some point after a fine spell first thing this morning.
