Free agent running back Kenjon Barner is signing with the Panthers, a source tells Ian Rapoport of NFL.com (on Twitter). Barner also visited the Bills before agreeing to terms with Carolina. 
The Panthers added C.J. Anderson earlier this week, but they found themselves in the running back market again after losing Fozzy Whittaker to a season-ending ACL tear. Barner ranks no higher than third at his position thanks to the presence of Christian McCaffrey and Anderson, but he can provide valuable depth as well as some support in the return game.
Barner, a 2013 sixth-round pick by the Panthers, spent the last three seasons with the Eagles. In 2015 and 2016, he was productive despite limited snaps, compiling 253 rushing yards on only 55 carries (4.6 yards per attempt). Last offseason, he signed a one-year free agent deal with the Chargers but returned to Philly after he missed the Bolts’ final 53-man cut. He saw less time at running back than ever in 2017, but he did average a respectable 8.9 yards per punt return.
