Andrew Flintoff could play a Twenty20 Cup game for Lancashire as part of his build-up towards a Test comeback.
Flintoff hopes to be fit for the second Test against Pakistan at Old Trafford on 27 July after spell on the sidelines baceuse of an ankle injury.
He has bowled in the nets and coach Mike Watkinson told BBC Sport there was "a bit of a chance" Flintoff could play against Notts on Sunday.
The final decision would, however, rest with the England and Wales Board.
Andrew Strauss will be captain for next week's first Test at Lord's, but Flintoff will take over when he returns to the side.
To be part of the squad for the second Test, Flintoff would first have to come through the four-day Championship game against Kent, starting on 18 July.
Chairman of selectors David Graveney has sounded a note of caution about the potential danger of Flintoff rushing his comeback.
"Freddie is making optimistic noises about when he might be available.
"There is no point in rushing him back too quickly if it impinges on his overall fitness," he commented.
Despite that, Flintoff plans to join the squad at Lord's next week and take part in practice sessions.
He is undaunted by the extra workload involved in leading the side, having done the job on tour in India earlier this year, and rang Graveney last weekend to confirm his desire to take on the captaincy again.
