Hampshire must make at least one change to their side for tomorrow’s crunch t20 clash with fellow high-fliers Essex at The Ageas Bowl.

Sohail Tanvir is unavailable as he has been called up to the Pakistan squad for their two t20 internationals against the West Indies.

The seamer’s call-up also means he will not be available for Hampshire’s t20 match against Kent at Canterbury on Monday night either.

Wicketkeeper Adam Wheater is included in the squad after not playing against Kent last Sunday and he could feature against his old club tomorrow.

Essex are likely to be unchanged from the side that beat Sussex by seven wickets on Sunday.

New-Zealander Hamish Rutherford and Australian fast-bowler Shaun Tait are both likely to feature for the visitors.

Hampshire could secure a place in the quarter finals if they win tomorrow and Surrey beat Middlesex tonight.
