The San Francisco 49ers are beating the Arizona Cardinals at half time in their NFL clash.

Phil Dawson's 27-yard field goal saw the 49ers take a 3-0 advantage, and they were soon further ahead when Anquan Boldin secured a touchdown from Colin Kaepernick's four-yard pass.

The first quarter ended with the 49ers easily on top and Vernon Davis added another touchdown to put his side in control.

Arizona began to emerge in the second quarter and were rewarded when Jake Ballard made it to the endzone for their first points of the match.
