Huddersfield Town's chances of securing a second signing of the window look to be on the up as Wolves agree a fee for Cardiff City striker Joe Mason.
Wanderers are desperate to strengthen their front line after selling Benik Afobe to Bournemouth earlier this month.
The 24-year-old Mason has scored six goals in 23 league games for Cardiff, who visit the John Smith's Stadium on Saturday.
However, that signing could mean that Rajiv van La Parra is allowed to leave the Midlands.
Town reportedly made a second bid for the forward after seeing their opening offer turned down. Able to play on the wing or up front, van La Parra could give David Wagner additional options to support Nahki Wells.
Although he is predominantly a winger, he can play up top - and has been used there by Wolves in recent games since the departure of Afobe. That adaptability could be key for David Wagner.
The 24-year-old Dutchman had a successful loan spell with Brighton earlier this season, scoring twice in six games but has struggled for game time under Kenny Jackett this term.
