DURHAM have a slight doubt about Graham Onions ahead of their final two group games in the Friends Provident Trophy, at home to Scotland on Sunday and Derbyshire on Monday.

The England Lions seamer has a sore heel and Durham could rest him as Neil Killeen will be fit to return.

In three of the four games which have gone to the wire, Onions has bowled the final over and secured victory at home to Yorkshire and Lancashire while being hit for six off the final ball at Old Trafford.

"We will see if his injury settles down," said coach Geoff Cook, who is keen to keep Callum Thorp in the team following his performances in the last two games.

"After a slowish start there's a lot of cricket coming up and wherever we can we have to avoid playing anybody who is not 100 per cent fit.

"It's also important that all our seamers get some bowling.

Liam Plunkett is close to being fit and will probably play for the second team at Tynemouth next week."

■ Tickets for England's NatWest Series one-day international against New Zealand at Riverside on Sunday, June 15 have sold out.

All 15,000 seats will be taken, but tickets are still available for the first Twenty20 international to be held at Riverside when England face South Africa on Wednesday, August 20.

The club's chief executive, David Harker, said: "It's been great to see the level of support that the region's sports fans have given to England's visits to the region this summer. The ODI is the first opportunity for our supporters to support Paul Collingwood at his home ground in his role as one-day captain and to do this in front of a sell-out crowd will be pretty special."

Tickets for the South Africa match are priced from £35.00 for adults and £10 for juniors. They can be bought online at www.durhamccc.co.uk
