LONDON (Reuters) - Relegation-threatened Hull City appointed Portuguese manager Marco Silva on Thursday to replace Mike Phelan until the end of the Premier League season.

Hull are facing a swift return to the second tier after securing promotion last May.

Silva, who resigned from Greek club Olympiakos Piraeus in June after leading them to a record 43rd league title, previously coached Estoril and Sporting Lisbon.

The 39-year-old becomes Hull's third manager of the season.
