Dragons have signed versatile back Thretton Palamo from Bristol on a one-month loan deal to cover injuries.

The 28-year-old United States wing or centre, a former Saracens player, will be involved on Friday when Dragons go to Belfast to face Ulster in the Pro14.

South Africa full-back Zane Kirchner dislocated a shoulder in Dragons' win against Connacht last Friday.

Dragons boss Bernard Jackman said: "He is a really good athlete. He is powerful and strong."
