Christian McCaffrey goes viral for insane musical performance with 5-week-old son

Christian McCaffrey drew attention online after sharing a video of himself playing harmonica while holding his five-week-old son, Roman. The San Francisco 49ers running back performed “Piano Man” alongside his brother-in-law Gus Culpo, continuing a musical side that has previously attracted attention.

The video follows Roman’s first visit to see his father play football, before the 49ers beat the Raiders 38-17. McCaffrey scored both a rushing and a receiving touchdown, gaining 68 yards on 18 carries. San Francisco has the NFC’s best record at 7-1 and is due to play the Cowboys away on Sunday.
