England injury worry as Cox hurts side while making century

Batter Jordan Cox appears to be an injury doubt for England's Test with Zimbabwe after he retired hurt on day three of Essex's County Championship match with Somerset.

The 24-year-old required treatment after falling to the ground clutching his left side, having run a single that took him to 99 in Essex's second innings.

Cox resumed his innings, hitting a boundary off Jack Leach to reach his century from 156 balls, and then immediately walked off the field, not returning for Somerset's innings.

The ex-Kent player was named in England's squad for their one-off Test with Zimbabwe at Trent Bridge from 22-25 May.

Cox is uncapped at Test level, having withdrawn from England's winter tour of New Zealand after breaking his thumb, but has played five white-ball games for his country.

He has been in good form in the County Championship this season, scoring 384 runs from six innings at an average of 76.80.
