Kamara (back) returned to practice Tuesday, Tom Pelissero of NFL Network reports.

While it was a lighter practice, according to Matthew Paras of NOLA.com, Kamara's return is certainly a positive sign. Kamara had been sidelined since Aug. 13 with back tightness. Given the veteran's status as the team's No. 1 option in the backfield, it would not be surprising to see head coach Dennis Allen continue to exercise caution with his availability going forward in preseason competition.
