Fulham boss Kit Symons has backed Marcus Bettinelli to move on from his goalkeeping error in the 3-1 defeat by Sunderland in the FA Cup fourth round.
The 22-year-old fumbled Patrick van Aanholt's deflected cross over the line to gift the Black Cats an equaliser.
"Marcus has been excellent for us this season and is a very popular character in the changing room," Symons told BBC London 94.9.
"He'll be disappointed but he'll bounce back from that without a doubt."
He added: "These things happen for goalkeepers from time to time. He won't let it affect him as he is a strong character."
Bettinelli has established himself as first-choice at Craven Cottage this season following loan spells at Dartford and Accrington earlier in his career.
However, his error cancelled out Hugo Rodallega's opener for Fulham, and Premier League side Sunderland went on to seal a place in the fifth round thanks to goals from Ricky Alvarez and Jordi Gomez.
"Sometimes if you are not playing particularly well and you get your noses in front, you need to hang onto it," added 43-year-old Symons.
"I'm disappointed with the performance as well as the result. I couldn't say we did enough to win the game."
Meanwhile, Symons says the west London club are still awaiting confirmation that Bryan Ruiz's loan move to Spanish side Levante has gone through.
The 29-year-old forward is set to move to the La Liga team on loan until the end of the season, with paperwork completed on Friday before the Spanish transfer deadline passed.
"The Football Association have confirmed our side of things was all in on time," said Symons.
"We are just waiting to hear from the Spanish side now and whether Fifa actually sanction it.
"They have not given us a timeframe - it can take four or five days for that to be confirmed. We are expecting it to be done but until it is actually confirmed, you never know."
