San Diego Chargers tight end Antonio Gates was at training camp on Thursday, but no one would have blamed him for missing it. The player is mourning the loss of his 22-year-old sister, Pamela.

Pamela died Wednesday after a three-year battle with lupus.

Recently, Gates had missed spring practices and told the public he was tending to a family situation.

On Thursday, it was reported Gates was often traveling after road games to visit his ailing sister in Detroit.

After practice, the all-pro football player said: “You basically get one chance to prove you love your family.”
