NEWPORT Gwent Dragons will be without Wales lock Cory Hill for Saturday's Guinness PRO12 clash with Glasgow (kick-off 3pm).

The 25-year-old forward will not be released from Six Nations squad duty because Rob Howley's side start their preparations on Sunday morning for the round four clash with Ireland in Cardiff.

Hill, who was a replacement against Italy and England and travelling reserve in Scotland last weekend, was sent out for game time against Connnacht a fortnight ago.

However, with the Irish encounter taking place on a Friday night he has been kept in camp along with colleagues from Cardiff Blues and the Scarlets because their regions play on Saturday.

The title-chasing Ospreys have a Friday fixture in Edinburgh so have been granted the services of props Nicky Smith and Rhodri Jones, lock Rory Thornton, back row forwards Olly Cracknell and James King and fly-half Sam Davies.
