The Buffalo Bills take on the San Francisco 49ers this Sunday at 1pm. The Bills defense will be facing 49er quarterback Colin Kaepernick under center rather than Week 1 starter Blaine Gabbert. Gabbert had struggled in the first five games of the season for San Francisco throwing for six interceptions. The 49ers have now lost four games in a row and sit in last place in the NFC West. Ryan Sakamoto of NinerFans.com joined Levack and Goz this afternoon and previewed this weekend's match up. Plus I had to ask him how he has become the most physically fit beat writer in the NFL! #BeastWriter. Make sure to follow Ryan on Twitter @SakamotoRyan
