The Detroit Lions have put defensive tackle Haloti Ngata on injured reserve.
Ngata left Sunday’s game against the Carolina Panthers with an elbow injury. He had two sacks in five starts this year.
The Lions signed defensive tackle Caraun Reid and defensive end Datone Jones. They also cut linebacker Thurston Armbrister on Wednesday.
Reid had a season-ending knee injury last season with the San Diego after playing in Detroit the previous two seasons.
The Minnesota Vikings put Jones on injured reserve last month before the season started. Green Bay drafted Jones No. 26 overall in 2013 and he had nine sacks with the Packers.
Detroit needs depth at defensive end because Ezekiel Ansah has been limited by a knee injury.
