Wrexham and Wales defender Stephen Roberts is set to join up with his brother Neil - a striker - at Doncaster Rovers.
The 25-year-old - out of contract in the summer - rejected a new deal offered by Denis Smith with a better offer from League One side Rovers.
Roberts was known to be keen to secure his long-term future after Wrexham's slip in to administration and relegation to League Two and will sign on 1 July when the transfer window opens.
Roberts made over 100 appearances for Wrexham, including playing a vital role in the north Wales side's winning LDV Vans Trophy campaign
