THURSDAY, 1:53pm: The Cowboys have officially announced the signing of Rivers, via a press release.
Rivers, who previously spent time with the Bengals and Giants, played just 12 games for the Bills in 2014, starting three. Of his 192 defensive snaps, nearly all of them came in the first half — the former ninth overall pick played just 24 snaps on defense after Week 8. After seeing his role dwindle in the second half of the 2014 season, the Bills opted to save $1.7MM by letting him go ($500K in dead money).
Rivers, a seven-year vet, spent 2012 and 2013 with the Giants. In his time with Big Blue, Rivers started 14 games and registered 83 tackles.
