Al told the Scotsman: "The hardest thing about being out injured is watching the team play without you, and especially when you lose, so it was very tough on Friday night to be at Firhill and watching that game go from us.
"Today, myself and Chris Cusiter are going through video analysis we have on Munster to begin the preparations for the game this Friday night and we're desperate to do whatever we can to help the guys get back to winning ways.
"Being asked to help with that side of things by the coaches has been good because it's given myself and Chris and other injured guys an involvement in what's happening week to week. I've been asked countless times whether I'll be back for Scotland in the autumn, and after being captain of the team in Argentina, where we created some great memories last time out, of course I'm desperate for that to happen.
"At the moment it's hard to say. The medics have said that if I keep going as I am now and we have no hiccups then I could be back in full training by the end of October, but then I have to prove my fitness and show form, because no-one can walk into a Scotland team.
"All that's in my head in the rugby sense right now is getting that Glasgow jersey back on."
