Fulham goalkeeper is devastated after a freak training ground injury ruled him out until February.
Fulham’s veteran American keeper had impressed since signing a one-year deal in the summer but tore his left bicep last week and may need surgery.
Former Spurs stopper Keller, 37, said: “I just wanted to make my name here and I was doing that until I suffered this cruel injury. I feel absolutely destroyed. I am devastated.
“I tore my left bicep. It started hurting after training and just got worse. It is hugely disappointing because things were going so well and then something like this comes along and I have to start all over again.
“I will probably be out for three to four months. It is a big setback.
“I signed a contract with Fulham until the end of the season.
“If surgery is the only option then I will have to go that route — and it is looking likely.”
In Keller’s absence Antti Niemi helped 10-man Fulham to a point against Derby with an excellent display.
The Cottagers’ Paul Konchesky was sent off for elbowing Craig Fagan just before half-time.
Keller added: “Antti did a great job and made two key saves to keep us in the game. It is important for us that he continues to play like that.
