Elsewhere, Leinster said centre Charlie Ngatai came through Friday’s dominant win over Connacht “with no issues” following his return from a shoulder problem.
However, number eight Jack Conan will be assessed through the week after being “withdrawn as a precaution”, while Tommy O’Brien has picked up a hamstring injury.
Leinster and Ulster meet for the third time this season with Ulster having claimed home and away wins during the regular URC campaign.
But having gained home advantage with a higher finish in the league, beaten Champions Cup finalists Leinster will aim to build on an impressive 33-7 win over Connacht.
Ulster, who lost 29-24 to Munster on Saturday, are expected to issue a squad update on Tuesday.
