Athletic Club's Iñaki Williams played with shard of glass in his foot for 2 years

Ghanaian soccer star Iñaki Williams unknowingly played two years with a two-centimeter shard of glass in his left foot, his coach revealed Friday.

Williams, who plays his club soccer for the Spanish side Athletic Club, underwent surgery on Tuesday to treat a painful scar on his left foot. It was then that they discovered a piece of glass embedded in the sole of his foot.

During a press conference on Friday, Athletic Club coach Ernesto Valverde said his player had permitted him to tell the story because "it is worth telling." He said the 29-year-old player was on vacation two years ago when he stepped on glass, resulting in a deep wound on his foot.
