Yorkshire v Somerset, Sussex v Notts, and more: county cricket, day one – as it happened

Action continues across the grounds as the battle for the County Championship Division One crown enters its decisive closing stages. Matches such as Yorkshire facing Somerset and Nottinghamshire traveling to Sussex headline the opening day's play.

Nottinghamshire bolstered their lineup just before the contest by drafting in pace bowler Mukesh Kumar. The seamer, who has amassed 233 wickets at the first-class level exclusively within Indian domestic competitions, links up with the squad immediately following a triumphant Duleep Trophy campaign with East Zone.
