A person with knowledge of the conversation tells The Associated Press that the new Alliance of American Football spoke with Colin Kaepernick during its development about joining the league.

But Kaepernick wanted $20 million or more to consider playing with the league that had its debut last weekend.

The person spoke on condition of anonymity Thursday because neither side has publicly acknowledged such talks.

The Alliance says its mission is to provide opportunities for players not in the NFL to continue their careers, with a possibility they could entice NFL teams to sign them once the AAF season concludes at the end of April. The league also approached Tim Tebow, who said he wanted to continue pursuing his baseball career. Tebow currently is in the New York Mets' spring training camp.

A message from the AP to Kaepernick's representatives was not immediately answered.

Kaepernick, then with the San Francisco 49ers, helped start a wave of protests about social and racial injustice in 2016 by kneeling during the national anthem at games. He has not played the last two seasons and has brought a lawsuit against the NFL for collusion to keep him out of the league.

He also fits the description for potential Alliance players, though his contract demands don't fit with the league's financial structure. After all, the AAF is entering its second weekend.

Players earn $225,000 over three years in the Alliance, but they also are free beginning in May to pursue NFL careers. Should they not catch on there, they are obligated to return to the AAF next season.
