Ulster coach Mark McCall has opted not to risk David Humphreys from the start of tonight's Heineken Cup match against Gloucester at Ravenhill, opting instead to play Paddy Wallace at outhalf.

An ankle injury meant Humphreys was doubtful but despite coming through a late fitness test the former Ireland player is named among the replacements.

Ulster are already without backrow Stephen Ferris who is out for four to six weeks with a knee injury.

Kick-off at Revenhill is at 8.00pm.

Ulster Team:B Cunningham; T Bowe, A Trimble, R Dewey, M McCrea; P Wallace, I Boss; J Fitzpatrick, R Best (Capt), B Young, J Harrison, C Del Fava, M McCullough, N Best, R Wilson

Replacements: N Brady, D Fitzpatrick, R Caldwell, K Dawson, K Campbell, D Humphreys, M Bartholomeusz
