David Luiz went into the away dressing room to apologise for concussing a teenage Brentford star in Chelsea’s 4-0 win on Sunday.
Jake Reeves was clattered into by the Brazil international late in the FA Cup fourth round replay at Stamford Bridge and was forced to leave the field.
Chelsea were four goals up at the time and the challenge was considered overly aggressive and unnecessary by many.
However, Brentford manager Uwe Rösler revealed after the game that Luiz had sought out 19-year-old Reeves in the dressing room to apologise for the challenge, which left him concussed.
“Jake is fine, he wanted to continue but our medical staff said it was better that he didn't," he said.
“They said: 'Safety first.' I have not seen the situation clearly enough to make a statement now but the player [Luiz] came into our dressing room and he spoke to Jake, which is a fantastic gesture. He apologised.”
Juan Mata, Oscar, Frank Lampard and captain John Terry all got onto the scoresheet in a dominant second half display by Chelsea, as the League One side’s resistance eventually faltered.
The win sets up a fifth round tie away to Middlesbrough and will be played next Wednesday, February 27 at the Riverside.
It was an enjoyable afternoon for Blues fans as Chelsea cruised to their third successive win since throwing way a lead at Newcastle United.
Interim manager Rafael Benitez will be hoping the run continues to relieve some of the dissent being aimed at him by angry supporters.
They will be expected to make it four-in-a-row on Thursday as they take a 1-0 lead from the first leg in their Europa League last 32 tie with Sparta Prague.
