Write an article that answers the following question: How many field goals did Prater kick in the first 2 quarters?
Hoping to rebound from their road loss to the Panthers, the Broncos went home for a Week 16 duel with the Buffalo Bills.  Denver stormed out to an early first-quarter lead as quarterback Jay Cutler got a 2-yard touchdown run, while kicker Matt Prater got a 23-yard field goal.  In the second quarter, the Broncos extended their lead as Prater made a 30-yard field goal.  The Bills got on the board with a 37-yard field goal from kicker Rian Lindell, followed by a 2-yard touchdown run from running back Marshawn Lynch. Buffalo took the lead in the third quarter as Lindell got a 49-yard and a 28-yard field goal, yet Denver regained the lead with Cutler getting a 6-yard touchdown run.  In the fourth quarter, the Bills answered with quarterback Trent Edwards completing a 3-yard touchdown pass to wide receiver Steve Johnson.  The Broncos would tie the game with Prater nailing a 43-yard field goal, but Buffalo got the lead again as running back Fred Jackson made an 8-yard touchdown run.  Denver put together a late-game drive, but it ended up fizzling down the stretch.
