Meanwhile Hogg's Gunners team-mate Marcus Di Rollo was examined by an orthopaedic surgeon last night and does not require a scan. "Marcus had taken a knock to his knee. That's settling down and he will be working on his rehab," Dr Haggerty added.
Scott Murray (ribs) and Hugo Southwell (thigh) also sustained injuries against the Barbarians and are receiving physio. All the injured players are being assessed on an ongoing basis.
