Tottenham Hotspur's Steven Caulker undergoes Cardiff City medical?

Tottenham Hotspur defender Steven Caulker is reportedly undergoing a medical at Cardiff City.

It was claimed earlier on Wednesday that the 21-year-old is poised to complete a move to the Bluebirds before the start of the new season.

The centre-back could now sign a deal with the Welsh club by the weekend, according to Sky Sports News.

Caulker signed a new four-year contract with Tottenham last summer.
