Wolves defender Jason Shackell's loan spell at Doncaster is being extended until the end of the season.

Centre-half Shackell arrived at the Keepmoat Stadium in mid-August and has become a virtual ever-present in manager Sean O'Driscoll's side.

The 26-year-old, who started out at Norwich before sealing a permanent move to Wolves in September 2008, has made 19 appearances for Doncaster and scored his only goal in the 3-1 home win over Peterborough in October.
