Tim Tebow rallied Denver for two touchdowns in the final 2:44 of the fourth quarter to force overtime, and Matt Prater's 52-yard field goal gave the visiting Broncos an improbable 18-15 victory Sunday over the stunned Miami Dolphins.

The Broncos (2-4) appeared beaten when they trailed Miami (0-6) 15-0 with 5:23 left and took over at their 20. At that point Tebow was 4 for 14 for 40 yards.

But he threw two TD passes sandwiched around a successful onside kick, and scored a 2-point conversion standing up with 17 seconds left to tie the game.

In overtime, Denver's D.J. Williams sacked Matt Moore to force a fumble and recovered it at the Miami 36. Three plays later Prater hit the game-winner.

Bears 24, Bucs 18: At Wembley, England, Matt Forte ran for 145 yards and a touchdown and Chicago (4-3) held on to beat Tampa Bay (4-3).

Panthers 33, Redskins 20: At Charlotte, N.C., Cam Newton ran for a touchdown and threw for another in the second half to help Carolina (2-5) beat Washington 3-3).

Jonathan Stewart also ran for a third-quarter touchdown for the Panthers, who for the first time all year found themselves playing with the lead almost the entire way.

Chiefs 28, Raiders 0: At Oakland, Calif., Kendrick Lewis and Brandon Flowers returned interceptions for touchdowns and Kansas City (3-3) took advantage of rusty quarterback play from Kyle Boller and Carson Palmer to blank Oakland (4-3).

Cowboys 34, Rams 7: At Arlington, Texas, DeMarco Murray ran for a franchise-record 253 yards, including a 91-yard touchdown that's the second-longest in club history, to lead Dallas (3-3) past St. Louis (0-6).

The Rams were without quarterback Sam Bradford and were averaging the fewest points in the league even with him.

Steelers 32, Cardinals 20: At Glendale, Ariz., Ben Roethlisberger threw 95 yards to Mike Wallace for the longest pass play in Steelers history and Pittsburgh (5-2) handed Arizona (1-5) its fifth consecutive loss.
