Manager Lee Bowyer wasn't happy with the amount of stoppage time allowed by referee Andy Davies as the Addicks drew 2-2 with Hull City.
Keane Lewis-Potter scored in the sixth minute of five minutes of stoppage time to equalise for the visitors after Charlton had led for much of the game.
He said: "We didn’t defend until the final whistle. That’s where we went wrong. You think we’d learn after Tuesday when the same thing happened. They scored with thirty seconds to go then and then tonight they scored in the injury time of injury time.
"They put up four minutes and then they decided to add on another minute. Then five minutes was up when the foul was given. Then the referee let them put the ball into the box, we cleared that… but I’ve been in the game long enough and every game I’ve seen once the clearance is gone then they blow. But no, he lets them play another cross in and then they score.
"Don’t get me wrong, it was bad defending, but now my lads… I feel for them so much because as you’ve seen there, they’ve given absolutely everything again. To get done like that when the whistle should have been blown - I'm gutted.
The Manager also spoke about players who are making their return to fitness. He said: "Lyle Taylor came on at the end there. He will now be ready to start a game. Jonny Williams will be training and will be on the bench as long as he comes through the training. Sam Field will be coming back to us on Wednesday from West Brom. I know the fitness coach and I know that he’s a had a good workout there and he’s ready to go from my understanding.
"Again, we have to bring these players back in again we can’t just say 'right, there you go there’s 90 minutes'. We have to break them in, a bit like what we have done with Lyle. But the positive is that we’ve got two more coming back next week.
"Before we lost Lyle we were six games in. we lost four and drew two. Then we had an international break, Lyle got injured and since then, we were okay without Lyle.
"We were still scoring goals and creating chances. We went to Fulham and West Brom with a lot of players out and got good results and were in the games. So I believe that once we get some of these players back – all of them would be great but I know how football works and I know you don’t always have a full squad – I’m sure we’ll start picking up more results.
"Again with all the bodies out we’re still competing and putting on a show."
