Flintoff wore Lancashire colours on Sunday

The England star, regaining fitness after a third ankle operation, played as a batsman only in the one-day match.

Lancashire cricket manager Mike Watkinson confirmed that Flintoff will now play in the Championship match against Sussex, starting on Tuesday.

Watkinson said: "He will be in the squad. There were no complaints at all and everything seems fine."

England paceman Sajid Mahmood, only two games back from a hernia operation, took 5-16 in the comfortable win.

Flintoff will not bowl in competitive cricket until Lancashire are satisfied his ankle can stand up to the stresses of bowling fast again.

The 29-year-old is eager to get back into action with a view to an England recall for at least part of the one-day international series against India, which starts on 21 August.

And his county may also field him on Twenty20 finals day on 4 August.

Flintoff took 10 balls to get off the mark before cracking four boundaries, the best a back-foot punch off left-arm seamer Gayan Wijekoon, before falling to the same bowler, playing all around a straight delivery.

Mahmood then skittled the top of the Sri Lanka A order for his first five-wicket haul in the limited overs game.

Lancashire's cricket manager Mike Watkinson saw enough to confirm that Flintoff will be available to play against the champions as a batsman only.

"He's going to go and take advantage of this good weather we have got, to go back into the nets," Watkinson said.

"The ball was nipping around a bit early on, and it was difficult to make scoring shots. He survived an early lbw shout that could have spoiled his day.
