CBS rejected the National Football League Players Association's "Let Them Play" ad which was supposed to air Feb. 5 on the CBS College Sports Network.
The commercial depicts life without football and features several players, including NFLPA president Kevin Mawae, and fans saying, "Let us play" or "Let them play."
The ad was scheduled to air during the NFLPA college All-Star game.
"I tried to have my team contact CBS to try to understand exactly what happened, but apparently they said they didn't want to get involved with the labor negotiations," said George Atallah, assistant executive director of external affairs for the Washington-based NFLPA.
