Doncaster have completed the double signing of forward Robbie Blake and winger David Cotterill.
Blake, 36, left relegated Premier League side Bolton Wanderers at the end of last season and has agreed a one-year deal with the option of a second.
Cotterill, 24, was released by Barnsley after a short-term deal last season and has signed a two-year contract.
"There are a few clubs who think they should be there [the Championship] and this is one of them," Cotterill said.
"I knew of the interest from Doncaster and Dean and obviously I have worked with him before."
"With the managers ambitions, he won't want to settle for second best - he's had a good career and is used to always winning."
The duo bring Dean Saunders summer acquisitions up to three, following the recruitment of midfielder David Syers from Bradford earlier this month.
