Carl Ikeme penned a new deal with Wolves before joining Doncaster Rovers on-loan yesterday.
The 25-year-old, whose current deal expired at the end of this season, has penned a three-and-a-half-year deal which keeps him at Molineux until 2015.
He said: "I enjoyed playing at Middlesbrough and will try to do the same for Doncaster. Beyond that, I want to push for the place at Wolves and wouldn't have signed if I didn't."
