Rugby:Ireland internationals Rory Best, Andrew Trimble and Stephen Ferris have not been rushed back into the Ulster squad ahead of the Pro 12 meeting with the Treviso at the Stadio Monigo (3.15pm Irish time).
Prop Tom Court has been included, however, despite a torrid time for around 45 minutes against England after he replaced Mike Ross at Twickenham.
The trio featured in the demoralising 30-9 defeat to England at Twickenham last Saturday and will be spared an instant return to competitive action with their province.
Brian McLaughlin has been able to recall captain Johann Muller and Darren Cave, however, after both missed around two months with a calf injury and foot injury respectively.
Phoenix Academy secondrow Iain Henderson is also included after his impressive Six Nations campaign with the Ireland under-20s.
Scot Simon Danielli is still struggling with injury, however, while Mike McComish is also ruled out after suffering concussion during the Edinburgh match earlier this month. Jared Payne and Declan Fitzpatrick also remain sidelined.
The league’s top tryscorers with 40 are fifth in the table and will be looking to maintain momentum against struggling Treviso, who have lost seven-in-a-row since the New Year.
