Reece Topley took six wickets as Essex dismissed Glamorgan for 244 on the opening day of their LV= County Championship Division Two match at the Essex County Ground.
Topley, making his first championship outing of the season after a stress fracture of his back during the winter, took 6-41 from 20.2 overs to help his side claim maximum bowling bonus points.
The hosts omitted Monty Panesar from their starting XI as a result of an issue with timekeeping, Tom Craddock included at his fellow spinner’s expense.
An Essex statement on Panesar, who will be available for the Eagles’ NatWest T20 Blast South Group fixture on Friday night, read: "Essex Cricket can confirm that Monty Panesar has been disciplined by the club after breaching team rules for timekeeping.
"Panesar has subsequently been dropped from the playing squad for the LV= County Championship match versus Glamorgan."

Left-armer Topley got to work in the second over, yorking Tom Lancefield after the visitors elected to bat.
The 20-year-old struck again just before lunch, having Ben Wright caught at gully, before returning with the new ball after tea to claim four wickets in five overs, including two in successive balls, to polish off the innings.
Glamorgan looked like they had recovered from a shaky start which saw them reduced to 94 for three just after lunch as Will Bragg passed 500 championship runs for the season in putting on 68 with Chris Cooke.
Bragg's departure for 93 in the penultimate over before tea was untimely to say the least as after the interval Glamorgan lost their last six wickets for the addition of just 53 runs.
Cooke was last man out, edging Topley to slip, just before the scheduled close for 68.
