49ers vs. Patriots score: Niners hold 17-3 lead at halftime

The San Francisco 49ers have had their way against the Patriots on Sunday Night Football. Despite facing sloppy conditions, a capacity crowd and the league's top offense, the 49ers hold a 17-3 lead at halftime.

Collin Kaepernick has played the best game of his professional career so far. He's completed eight of his 15 pass attempts for 107 yards and two touchdowns. He's also carried the ball five times for 29 more yards. His first touchdown strike was a 24-yard pass to Randy Moss on San Francisco's first drive of the game. With the score 7-3 midway through the second quarter, Kaepernick hit Delanie Walker along the sideline for a 34-yard touchdown.

The 49ers got the ball one final time in the closing minutes of the half. Despite having a couple of shots at the end zone, they ended up settling for a 20-yard field goal from David Akers as the clock expired.

Tom Brady has been unable to get much of anything going. The veteran quarterback has thrown for just 76 yards and an interception while completing 10 of his 19 pass attempts. New England's running game has also been held in check; on 12 combined carries, Danny Woodhead and Stevan Ridley have just 43 rushing yards.

The second half is about to get underway on NBC.
