Kevin Nolan has featured only once for West Ham this season due to a fractured shoulder sustained in training.
In an interview with West Ham's website he has revealed how it happened, and when he aims to return.
He said: "It was an unfortunate incident really, I've ended up falling straight down on my shoulder and all my weight landed on it which forced it to crack.
"The added pressure of Carlton Cole falling on top of me didn't help, but you know it's one of those unfortunate incidents."
Nolan added that he hopes to be back within a month, already two and a half weeks into an estimated six week recovery period, although a more conservative timescale can be eight weeks.
"As it goes along I'll find out more about what I can do with it. In the end it'll come down to how much pain threshold I can take really."
The fixtures West Ham stand to miss without Nolan include the following over the next month:
Hull (a), Liverpool (h), Manchester United (a), QPR (h). Then there is another international break in mid-October and Nolan may just be available in time for October 18 away at Burnley, and if not, a week later away to Manchester City could be a more viable return date.
His absence will allow new signing Alex Song time to shine in midfield and settle. What they will hope for is that striker Carlton Cole can make as telling an impact on the pitch, than he did off it.
