WATCH: Arik Armstead, Javon Kinlaw combine for sack vs. Cowboys

49ers rookie DLJavon Kinlaw should get some credit for helping Arik Armstead sack Cowboys QB Andy Dalton.

Javon Kinlaw won’t get credit for a sack on a third-and-6 for the Cowboys, but he certainly deserves some. Arik Armstead blasted through a wide open hole for a huge sack thanks to a move by Kinlaw that cleared out the Cowboys’ right guard and right tackle. Armstead timed his rush perfectly to get in behind the big rookie for sack No. 2.5 of the season.
