The Seattle Seahawks lead the Arizona Cardinals 15-7 at halftime in Arizona. Here are highlights from the first half:

• Arizona's first offensive snap could've gone a lot better, as Seahawks safety Kam Chancellor forced a fumble of Cardinals running back Adrian Peterson. Chancellor's fumble was recovered by Seahawks defensive lineman Sheldon Richardson and taken to the 48. The Seahawks unfortunately couldn't capitalize off the turnover and went three-and-out on offense on their ensuing possession.
• Seahawks defensive tackle Jarran Reed has been ruled out of the game with a hamstring injury. Reed sustained the injury in the first quarter.

• Russell Wilson found Jimmy Graham for a 6-yard touchdown to score the first points of the game. Graham has scored all five of his touchdowns this season in the past five games.
• The Seahawks defense recorded a safety for the second week in a row. Chancellor, K.J. Wright and rookie Nazair Jones were huge in stuffing Peterson behind the line of scrimmage on Arizona's fourth offensive drive. Seattle has recorded safeties in back-to-back games for the second time in franchise history, with the last time coming in 1993.

• Seattle has struggled to minimize penalties in the first half after committing 16 last week against Washington. The Seahawks have recorded eight for 81 yards at the moment. 
• A 23-yard run by Thomas Rawls on Seattle's final offensive drive of the half was his longest of the season. The Seahawks would tack on a 33-yard field goal to cap the possession.

• Seahawks left tackle Duane Brown injured his ankle near the end of the half and is questionable to return. Matt Tobin took over for Brown on the snaps he missed while being evaluated. 
• It's shaping up to be an impressive day for Chancellor, who in addition to forcing a fumble and setting up a safety has tallied a game-high six tackles at the break.
