Doncaster have signed winger John Oster on a short-term contract.
The former Wales international has been on trial with Rovers and has impressed manager Sean O'Driscoll sufficiently to earn himself a contract.
The 30-year-old, who has made 13 appearances for his country, joined Everton from Grimsby in a £1.5 million deal in 1997 before switching to Sunderland two years later.
Oster has also enjoyed spells at Barnsley, Leeds, Burnley, Crystal Palace and Reading.
