Brian Stock and Lewis Guy have become the latest players to sign new contracts at Doncaster Rovers.
The Championship newcomers saw James Coppinger and James O'Connor agree extensions earlier in the week, and now Stock and Guy have followed suit.
Stock, who had 12 months remaining on his previous deal, has accepted an extension to stay at the Keepmoat Stadium until 2011.
Improving striker Guy has settled upon a one-year top-up to his Doncaster contract to commit himself to Sean O'Driscoll's men until 2010.
In addition to the four new contracts, O'Driscoll has also added to his squad this week with the signings of Matthew Mills and Jos van Nieuwstadt.
