Heidar Helguson has put pen to paper on a loan deal with Watford until the end of the season.

The Icelandic front-man has penned a deal until June 30th 2010, but under the terms of the deal is not eligible to play against the R's when the Hornets visit Loftus Road in mid-February.

Helguson enjoyed a successful spell with the Golden Boys earlier this season, scoring five goals in 10 appearances.
