Lions sign David Fales as backup QB option, cut Connor Cook
Detroit also added offensive lineman Luke Bowanko and released safety David Jones on Monday.
Fales replaces Cook as a backup candidate behind Matthew Stafford and Tom Savage. Fales, who played in Miami the previous two years, has completed 29 of 43 passes in his career for 265 yards with one touchdown and an interception. The former San Jose State star was drafted in 2014 by Chicago in the sixth round.
Cook, a former Michigan State star, played in one game for the Oakland Raiders in 2016.
