For Kansas City Chiefs defensive back Tyvon Branch, Sunday's game is like a family reunion—only the two sides of his "family" are historic AFC West rivals.

Branch came to play for the Chiefs after spending seven seasons with the Oakland Raiders.

He was drafted in the fourth round of the 2008 NFL Draft by Oakland.

From 2008 to 2014, Branch racked up 461 tackles (355 solo), 25 tackles for loss, 8.0 sacks for 83 yards lost, 12 quarterback pressures, 3 forced fumbles and 4 fumble recoveries on top of 4 career interceptions.

The Chiefs picked up Branch in the offseason to complement a defense that ranked No. 2 in the entire National Football League, with a secondary that didn't allow a 300-yard passing game to any quarterback in that season.

Branch spent the 2013 and 2014 seasons sidelined by injuries, but his arrival in Kansas City represented a new chance for the eight-year veteran.

"I had some setbacks and I'm just excited to have another opportunity," Branch said last spring. "Every opportunity you get to play this game is a blessing, and I'm blessed to have an opportunity with the Kansas City Chiefs."
