Hey football fans: Are you ready for Brady-Osweiler I in two weeks?

You might not have a choice. The NFL's storied quarterbacking clash between Peyton Manning and Tom Brady is in serious jeopardy now.

Manning might still be sidelined with a torn foot ligament. Or, the Broncos might shut down a healthier Manning in hopes his arm regenerates for a run. Either scenario would prevent Brady-Manning XVII from happening in two weeks.

That's a shame; the two quarterbacks could've restored the luster lost when Manning and the Broncos lost two weeks ago.

Now, the matchup will probably feature only one undefeated team -- and only one all-time great quarterback.
