Women's groups are calling on CBS to scrap a planned Super Bowl ad featuring college football star Tim Tebow and his mother, which critics say is likely to convey an anti-abortion message.
A protest letter sent to CBS says the ad "uses sports to divide rather than to unite." The National Organization for Women is among the groups backing the protest.
A spokesman says CBS approved the script and gave no indication the protest would have an impact.
The Christian group Focus on the Family paid for the 30-second ad. It's expected to recount the story of Pam Tebow's pregnancy in 1987. After getting sick on a mission trip to the Philippines, she ignored doctors' recommendations to have an abortion and gave birth to Tim.
The Heisman Trophy winner has led Florida to two BCS titles.
