Player holds ball between his knees-NCAA

[voiceoflg]

In an NCAA game Saturday night, a player on Team A bobbles a pass while slipping down. When his butt hits the floor, the ball is between his knees. A Team B player grabs the ball but Team A guy has the ball so tightly Team B player picks the prone player's butt and back off the floor while holding the ball. I'm thinking traveling but one official ruled jump ball.

What's the correct call? It didn't affect the outcome as Team A won by 23.

Thanks.
