The San Francisco 49ers placed wide receiver Bruce Ellington on season-ending injured reserve Tuesday after he tore a hamstring muscle last Friday.
Ellington, 25, missed the team's second preseason game with an ankle injury. He has dealt with ankle and hamstring injuries throughout his two-year career.
In a corresponding move, the 49ers traded with the Detroit Lions for wide receiver Jeremy Kerley to add depth and give them a viable slot option.
New 49ers coach Chip Kelly had lauded Ellington's abilities during camp, setting him up for a breakout campaign on offense after he had played mostly on special teams his first two seasons.
Ellington, who has 19 receptions for 215 yards and two touchdowns in 26 career games, will enter next season with just one year left on his rookie contract.
