What happens if an umpire ends a cricket over after the wrong number of valid balls?
An ordinary over contains six valid balls, but the MCC Laws make the umpire’s mistaken count stand if the umpire miscounts. If the mistake lets play continue after six valid balls, the umpire calls Over after a later delivery becomes dead, even when that delivery is invalid. No additional valid ball is needed, and a call of Over is never made while the ball is live.

Six valid balls make the normal over
Overs alternate between ends and contain six valid balls. An over starts when the bowler begins the run-up, or, without a run-up, begins the action for the first delivery. A normal call of Over follows the sixth valid ball only after the ball has become dead. A ball must have been delivered to count, and a No ball or Wide does not count toward the ordinary six.
Treat the umpire’s delivery classification and whether the ball is dead as separate inputs. Under Law 20.7, a delivered ball called dead before the striker has an opportunity to play it does not count in the over. After an opportunity, it is ordinarily a valid ball unless a No ball or Wide was called or an over-count exception applies under Laws 20.4.2.6, 24.4, 28.2, 41.4 or 41.5; the 20.4.2.6 distraction case does not count. For the readiness case in 20.4.2.5, a delivery does not count only when both conditions hold: the striker makes no attempt to play it and has an adequate reason for not being ready. Otherwise that branch is a valid ball, subject to other applicable invalid-ball rules. A call of No ball or Wide does not, by itself, make the ball dead.
The two kinds of counting mistake have different outcomes
If the umpire mistakenly calls Over after too few valid balls, the over as counted by that umpire stands. The viewer’s tally does not replace the official count.
If the umpire’s miscount allows the over to continue after six valid balls, the umpire calls Over once the ball becomes dead after any later delivery. That later delivery may be invalid. It does not become a valid ball because it closes the over, and the umpire must not call Over while that delivery is live. This rule explains when an over is closed; it does not establish score deletion, replay rights or a general method for correcting an official record.
A short count and an overrun delivery
In an anonymous fictional innings, officials classify all deliveries in advance for this example; no injury, participant change or welfare event is involved. In one over, the umpire mistakenly calls Over after five valid balls. The count used by the umpire stands under Law 17.5.1. In a separate over, six valid balls have already been delivered, but the umpire mistakenly permits another delivery. That extra delivery is stipulated to be a Wide and later becomes dead. Under Law 17.5.2, the umpire then calls Over; no further valid ball is required before that call. The Wide remains invalid and does not become an ordinary valid ball.

Does a Wide call alone end the delivery?
No. The call itself does not make the ball dead. In an overrun, the umpire closes the over when the later delivery becomes dead; its invalid status remains unchanged.
