“Thanks everybody for the messages, won't be long til I'm back,” Richards wrote on his Instagram account Wednesday.
Palace manager Oliver Glasner didn't have a timetable for when Richards would return.
Palace hosts Tottenham in the Premier League on Sunday, then welcomes Fulham on New Year’s Day.
“He got a knock on his foot, a stamp on his foot, and it had to be stitched,” Glasner said about Richards after the game against Arsenal. “I don’t know how many stitches, but a few.
“The doctor told me it doesn’t look so bad. I’m always hopeful. We have to be hopeful. I don’t know if he will be OK for the Tottenham game, but I’m still hoping that he will be back against Fulham.”
The 25-year-old Richards has been a regular starter for the U.S. He missed the 2022 World Cup because of a leg injury.
Arsenal beat Palace 8-7 on penalties following a 1-1 draw after 90 minutes.
