Johann van Graan rings the changes for Munster while Baloucoune replaces Stockdale for Ulster
Ian Nagle will make his first start for Ulster when a Munster side, featuring 13 changes, visits Kingspan Stadium on Friday evening (kick-off 7.35pm).
Nagle of course, replaces Iain Henderson after the Irish lock's surgery on a thumb injury.
Also in Ulster's pack, Rob Herring comes in as captain to replace Rory Best, who is named among the replacements.
Academy winger Robert Baloucoune is the third addition to the line-up with Jacob Stockdale dropping out of the squad.
Eric O’Sullivan and Marty Moore will join Herring in the front row, while Kieran Treadwell will pack down beside Nagle in the second row. The loose forward combination of Sean Reidy, Jordi Murphy and Marcell Coetzee is unchanged.
Alongside Baloucoune in the back three are the experienced Louis Ludik and Henry Speight.
The half-back axis of John Cooney and Billy Burns is retained along with the midfield pairing of Stuart McCloskey and Will Addison.
Kyle McCall, Nick Timoney, Dave Shanahan and Johnny McPhillips all hold their places on the bench while Ross Kane, Clive Ross and James Hume replace O'Toole, Rea and Cave.
