This weekend was a big one for Tottenham loanee Milos Veljkovic, but it did not end well.
Regarded as a centre-back at Spurs, Veljkovic was handed a start in central midfield, just like in his previous two matches since his switch to Charlton.
However at the Riverside it did not end well, Veljkovic was taken off injured after landing awkwardly following a challenge in the 34th minute.
Charlton manager Guy Luzon was not especially positive after the game when asked if it looked like a 'bad injury', via comments made to the club's official website:
He said: "Yes, unfortunately. "Miloš arrived to us two weeks ago and had started to be an important player in our squad, but it he has hurt his shoulder.
"From what I have heard in the good case he will be out a couple of weeks and in the bad case it could be a couple of months. I hope that he will be OK and feeling good."
Charlton went onto lose the game 3-1, and sit in 19th in the Championship table.
Unlike at Middlesbrough, where he was in and out of the side, usually on the bench, Veljkovic had earned the trust of his boss to command a starting spot early upon arrival.
If he is to miss a couple of months then it will stop his season in his tracks, just when he was at a crucial phase of his development, and both he and the Addicts will be hoping for a positive fitness update this week.
