(KSDK Sports) -- They may have been a little late for Halloween, but Week 10 in the NFL may be best known for the zombie-like invasion of the backup quarterbacks. Because of injuries, several teams had to start their second-stringers; others were forced to go to them when their starters went down.

The most successful of the bunch turned out to be lightly regarded Kellen Clemens of the St. Louis Rams. Clemens got some help from touchdowns by his defense and special teams -- but was quietly effective in his own right, completing nine of 16 passes for 247 yards and two touchdowns.

Those two TDs both went to the breakout star of the week, rookie wide receiver Tavon Austin, who caught scoring passes of 57 and 81 yards -- and also returned a punt 98 yards for another touchdown. It was the kind of big-play day fantasy owners had yet to see all season from Austin. In fact, Austin had only 207 receiving yards and two touchdowns in the Rams' previous nine games.

Unlike the Nick Foles-to-Riley Cooper connection that paid dividends for a second consecutive week (Cooper had two more TD receptions on Sunday), don't bank on Clemens-to-Austin carrying fantasy teams to new heights going forward. Those were Austin's only two receptions the entire game.
