USA international Paul Mullen has joined Newcastle Falcons for the first four months of the Premiership season as the club bolsters its propping stocks.
Born and raised in Ireland, the 26-year-old was part of Munster's Under-20s squad before relocating to the USA to further his studies.
Speaking after completing his move to Kingston Park, Mullen said: "I am delighted to be joining Newcastle and am looking forward to developing my game further alongside a great squad."
Falcons director of rugby Dean Richards said: "Paul has broken through to the full international scene in quite a big way over the past few months, and been part of a rapidly-improving American Eagles side.
"His presence will further bolster our front-row resources going into the new Gallagher Premiership season as we look to improve yet again on what was our best league finish for 20 years."
Mullen’s arrival comes on the back of the previously-announced signings of George McGuigan (Leicester Tigers), Pedro Bettencourt (Carcassonne), Logovi’i Mulipola (Leicester Tigers), Guy Graham (Hawick), Tom Arscott (Rouen), Connor Collett (North Harbour), Nemani Nagusa (Aurillac) and Johnny Williams (London Irish), as well as senior academy promotions for England Under-18s stars Cameron Nordli-Kelemeti, Morgan Passman, Will Montgomery, Tom Marshall, Josh Hodge and Rob Farrar.
