Colts quarterback Andrew Luck surpassed Cam Newton's year-old record for yards passing by a rookie when he had 123 in the first half of Sunday's game against the Chiefs.
Luck needed only 74 yards to break the Carolina quarterback's mark of 4,051 yards, and he eclipsed it while leading the Colts to a field goal that gave Indianapolis a 13-3 halftime lead.
The Colts could clinch a playoff berth with a victory over the Chiefs.
Luck has already led the Colts to victory six times in the fourth quarter, a rookie record for a quarterback. His 20 touchdowns are well off Peyton Manning's record of 26 set in 1998.
