Bell signed the low tender offer worth $1.26 million over one season, as opposed to a long-term deal. The Bears tendered a qualifying offer to the veteran back in March.
Bell broke the news on his Twitter account on Wednesday afternoon.
"Just re-sign[ed] with the Bears today going on year number 4!!! God is so great. Blessed beyond belief!!!"
Bell appeared in 13 games with the Bears last season, including three starts, and rushed for 337 yards.
