Ulster have made 10 changes to their starting side for the trip to Italy to face Zebre in a 3pm kick-off.
And Munster head coach Anthony Foley will be hoping to a large crowd at Thomond Park as they play host to an Ospreys side that have made a strong start to the Pro12 campaign and will be targeting a return to the top of the table.
Kick-off in Limerick is at half-past six.
