It will re-start for him at The Valley on Wednesday night when he lines up for the reserves against Charlton in the FA Premier Reserve League.
The striker has yet to feature in the Premiership after picking up a groin injury in the latter stages of pre-season.
It’s been a frustrating time for the 29-year-old who was desperate to carry over his goal-den streak from last term when he scored nine goals in his last 13 games.
Once again, injury has denied him the opportunity — but now he’s on the mend again.
Armstrong reflected: “I’m just waiting for the season to start really. I’ve played one-and-a-half reserve games, had a little setback and now I’ll be looking to get 90 minutes under my belt at Charlton on Wednesday.
“I had a slight strain of the abdominal muscle but it was only a few days missing training, a bit of treatment and I was back out again.
“I’d done quite a lot of training before it happened, a couple of double sessions and a reserve team game and maybe there was a little strain put on it but it was nothing too serious. Now with the internationals I’ve got extra time to get back.
“There is no game this weekend so I can get a couple of reserves games under my belt, work on my fitness and hopefully by the time the next game comes around I’ll be there or there abouts.”
That target is Coventry City on Saturday October 14.
