The trade comes less than a week after Lions GM Brad Holmes expressed hope of keeping Montgomery in Detroit. Montgomery was unhappy with his reduced role last season when he had career-lows in rushing yards, attempts, and touches while playing as the clear No. 2 behind Jahmyr Gibbs.
The 29-year-old Montgomery is scheduled to make $6 million this fall in the first year of a two-year extension. The Lions save approximately $3.5 million in cap space with the trade and now need to find a replacement running back. Potential options mentioned include Brian Robinson, Najee Harris, and Michael Carter.
