Connacht coach Michael Bradley has made seven changes to the side that lost 18-11 to Llanelli last time out Veteran Eric Elwood gets the nod at number ten.
Mark McHugh and Chris Keane also return in the backs, with Dan McFarland, John Fogarty, Stephen Knoop and John O'Sullivan recalled up front.
With Humphreys involved in tomorrow's IRB Tsunami Rugby Aid match at Twickenham, Adam Larkin is recalled to the Ulster line-up to partner Kieran Campbell at half-back.
In all, coach Mark McCall has made three changes for the visit of Glasgow to Ravenhill. Simon Best switches to tight-head to accomodate the inclusion of fellow prop Ronan McCormack.
While hooker Paul Shields starts for the first time since January 16, in place of the benched Rory Best.
Ulster lost 13-11 at the Dragons two weeks ago, but are unbeaten in five games at their Belfast home.
