Title:
Super_Bowl_50

Context:
On Carolina's next possession fullback Mike Tolbert lost a fumble while being tackled by safety Darian Stewart, which linebacker Danny Trevathan recovered on the Broncos 40-yard line. However, the Panthers soon took the ball back when defensive end Kony Ealy tipped a Manning pass to himself and then intercepted it, returning the ball 19 yards to the Panthers 39-yard line with 1:55 left on the clock. The Panthers could not gain any yards with their possession and had to punt. After a Denver punt, Carolina drove to the Broncos 45-yard line. But with 11 seconds left, Newton was sacked by DeMarcus Ware as time expired in the half.

Question:
Who tackled the Carolina Panthers' quarterback just before the end of the first half?

DeMarcus Ware
