Midfielder set to be out for four to eight weeks.
Two weeks ago Danny Redmond suffered a knee injury after being caught by an opposition player's studs when Latics took on and beat Barnsley in the Professional Development League.
At the time of the collision Redmond didn't expect the injury to be as serious as it was.
“There’s quite a lot of bruising on my knee and I’ve got a little hole in my muscle.
“At the time of the challenge I thought it was just a dead leg and grabbed my knee with the pain and my hand was wet, so I looked down and there was blood on my knee.
“I knew then that it was a bit more serious than a dead leg and that’s when the physio came on and said I’d need stitches.”
The 21-year-old had a scan on his knee last week and was hopeful of a quicker return than expected.
“I’m going to be out for four to eight weeks but that is the worst case scenario, hopefully I can be back a lot sooner.
“After I’d been taken off I went to see Barnsley’s doctor and physio, because it was quite a serious injury and my knee needed attention straight away.
“An injury like this at the time needs to be cleaned to prevent infection which would make it worse.
“I’m already in the rehab process now and at this stage it’s just about trying to get the injury to heal and I’ll be doing some work in the gym to keep up my fitness.”
It was 30 minutes in to the 2-1 victory when Redmond was forced off and at the time he believed all was well, saying:
“I thought I was having a good game at the time and I was really enjoying it.
“I couldn’t believe it when it happened because everything was going so well in the game and we seemed to be in a lot of control which I was enjoying playing a part of.
“I’m disappointed with the injury because there’s obviously the FA Cup game coming up at the weekend but I’m sure the lads can do the job and then hopefully I’ll get another chance when I’m fit again.”
