Skysports.com understands Dagenham & Redbridge have accepted a bid from an unnamed Championship club for Danny Green.
Both Peterborough and Charlton have been chasing the signature of the goalscoring midfielder, who netted 13 goals for the Daggers last term despite being relegated to League Two.
Dagenham reportedly rebuffed bids from both clubs earlier in June, but it would appear they have found the latest offer too good to turn down.
Posh had already seen two bids for the player rejected, but are still rumoured to be keeping a vested interest in the 22-year-old.
Green arrived at Dagenham an unknown from non-league outfit Bishops Stortford in 2009, and helped the club to gain promotion to the third tier of English football for the first time in their history.
Details of a possible fee have yet to be released for the player, but manager John Still will be looking to coup a significant amount as he looks to reinforce his squad in time for the new season.
