Five nuggets of knowledge for the Week 13 games:

Newton making history: Carolina quarterback Cam Newton is 54 yards short of 500 rushing yards. If he reaches it, he will become the first quarterback in NFL history to rush for 500 yards in each of his first two seasons.

Enjoying the road: The Panthers have a chance to win their third consecutive road game, at Kansas City on Sunday. Carolina has won its past two road games after ending a streak of four straight road losses. The Chiefs are 0-6 at home this season. That’s their first 0-6 home start since 1976. Kansas City never has started 0-7 at home.

Next man up: Call it bad luck that the Tampa Bay Buccaneers have a league-high $37.89 million in salaries on injured reserve this season. That total is led by the high salaries for guards Carl Nicks and Davin Joseph, defensive end Adrian Clayborn, linebacker Quincy Black, and offensive tackle Jeremy Trueblood. But also give credit to the Bucs for having a winning record and being in the playoff hunt despite missing a bunch of key ingredients.

Strength on strength: Denver’s defense has allowed a league-low eight completions on throws of more than 20 yards downfield. Tampa Bay quarterback Josh Freeman has completed a league-high 22 passes of more than 20 yards, according to ESPN Stats & Information.

Headed for the record book: Tampa Bay rookie running back Doug Martin is second in the NFL with 1,382 yards from scrimmage. No rookie has led the league in yards from scrimmage since Eric Dickerson in 1983. Martin needs 59 yards to break Warrick Dunn’s franchise record for yards from scrimmage by a rookie.
