Four of the six Ulster players that helped Ireland to their record win over England at the weekend are available to Mark McCall ahead of this weekend's Celtic League game against Llanelli Scarlets in Stradey Park.
Scrumhalf Isaac Boss, who ran in the fourth try against England, will join back up with the squad alongside fellow Irish substitutes Andrew Trimble, Simon Best and Paddy Wallace.
Ireland's starting hooker this year, Rory Best, will not be availablt to McCall, as is the case with flanker Neil Best who sat out Irish training yesterday with a dead leg.
Ulster fans may also get a chance to see new signing Sam Harding make his debut in the competition.
Ulster are currently second in the Celtic League, two points behind Leinster, who this morning announced plans for a friendly against Italian side Benetton Treviso.
Michael Cheika's men will take on the Italians in Donnybrook on March 14th to help the squad prepare for the business end of the Celtic League and European Cup.
Treviso faced Leinster's European Cup quarter-final opponents Wasps in the Pool stages of the tournament.
The province convincingly beat them on two occasions in the 2004/05 season when they met in Europe.
