According to Jones' agent Mike McCartney, the 49ers have signed DT Chris Jones to a one-year deal.

After being released by the Dolphins mid-season, Jones was picked up by the 49ers to boost their horrible run defense.  

Jones ended up making six starts in which he recorded 17 tackles, his biggest game coming against the LA Rams, where he recorded six. 

Although the San Francisco 49ers' run defense was terrible all year, it seemed to improve with Chris Jones on the field. The 26-year old was able to be an ideal stopgap and provide solid depth for a defensive line that desperately needed it.

Jones was originally a draft pick of the Houston Texans, where the current 49ers defensive line coach, Jeff Zgonina, was the assistant defensive line coach.

It'll be interesting to see what role he plays this upcoming season, but he's one of the few free agents from 2016 that'll be returning to the 49ers in 2017.
