London Welsh head coach Lyn Jones says his team will fight until the end as they look to avoid relegation from the Aviva Premiership.
Last month the club were deducted five points and fined £15,000 for fielding ineligible player Tyson Keats.
The penalty leaves them bottom of the table, eight points adrift of 11th-placed Sale with three games to play.
"We're still there and still fighting and we intend to come out and play a bit of rugby," Jones told BBC Oxford.
The club host Northampton this weekend and Jones admits the penalty from the Rugby Football Union has had a deep effect on everyone at the club.
"With the five point deduction it has been difficult for us," he said. "It has taken away a lot of the energy at the club and people working at the club.
"It's like a member of your family passing away really. It takes a lot of time to recover from the kick in the stomach.
"All the hard work everyone at the club has put in has been for nothing and that is a difficult one to take.
"But we are forgiving people and we need to move on and get over it as quickly as we can."
