Munster have confirmed the signings of Argentina full-back Lucas Gonzalez Amorosino and Brumbies flanker Sean Doyle on three-month deals.

Doyle is covering for the injured Peter O'Mahony, while Amorosino comes in following the retirement of Felix Jones.

Amorosino is in the Argentine World Cup squad and was on the bench as the Pumas defeated Ireland in the quarter-finals.

Doyle has previously played for Ulster.

Meanwhile, Munster have included Simon Zebo on the wing for tomorrow's Guinness Pro12 derby against Ulster at Thomond Park.

The returning Donnacha Ryan is on the bench, while scrum-half Tomas O'Leary makes his first start for the province since returning in the summer.

Ulster have included both Darren Cave and Paddy Jackson in their starting side, while Chris Henry is named on the bench after their involvement in Ireland's World Cup campaign.
