College Football/illegal touch, player out of bounds
Is there NCAA ruling for a player that goes out of bounds and re-enters the field to make a catch (making him an ineligible receiver), who ALSO turns the ball over on the same possession--that negates the play, and subsequently the turnover?
There is a rule. Rule 7-3-4 provides that "No eligible offensive receiver who goes out of bounds and returns in bounds during a down shall touch a legal forward pass while in the field of play or end zones or while airborne until it has been touched by an opponent or official." He is ineligible, but if he returns and makes the catch, it is a live-ball foul. Therefore, it would not negate a turnover, as the defense would merely decline the penalty. (Penalty is loss of down at the previous spot.) That said, he must reestablish inbounds. If he jumps from out of bounds, then as soon as he touches the ball, it is out of bounds, and is an incomplete pass immediately.
Now, there is an exception to this rule. If an otherwise eligible receiver goes out of bounds due to contact by an opponent, and immediately returns inbounds, he remains eligible.
I hope that helps.
