NFL-Broncos clinch playoff berth by stomping Titans

Dec 8 (Reuters) - The Denver Broncos and quarterback Peyton Manning clinched a berth in the National Football League playoffs by stomping the visiting Tennessee Titans 51-28 on Sunday. Matt Prater kicked an NFL record 64-yard field goal to help spark the win. The victory improved the AFC West-leading Broncos' record to 11-2 with the second-place Kansas City Chiefs at 10-3 with three weeks remaining in the season. Denver, with two wins against the Chiefs this season, holds the tiebreaker edge over Kansas City. Manning completed 39-of-59 passes for 397 yards and four touchdowns in Sunday's victory over the 5-8 Titans. (Reporting by Larry Fine in New York, Editing by Gene Cherry)
