Larkin in to replace Humphreys

Adam Larkin has been added to the Ulster squad as cover for David Humphreys ahead of their Magners League tie with Glasgow on Saturday.

Humphreys hurt his left arm in the first few minutes of Sunday's game against Leinster at Lansdowne Road. An MRI scan has revealed a degree of bruising from the impact and significant soft-tissue damage.

Larkin will provide cover for Paddy Wallace at out-half in the 23-man squad as Ulster bid to keep their lead at the top of the league.

ULSTER (v Glasgow):

BACKS: Kieran Campbell; Isaac Boss; Adam Larkin; Paddy Wallace; Kevin Maggs; Paul Steinmetz; Andrew Trimble: Paul McKenzie; Mark Bartholomeusz; Bryn Cunningham; Tommy Bowe.

FORWARDS: Simon Best (captain); Bryan Young; Justin Fitzpatrick; Rory Best; Paul Shields; Justin Harrison; Matt McCullough; Tim Barker; Roger Wilson; Neil Best; Kieron Dawson; Neil McMillan.
