According to the Detroit News, the Detroit Lions are signing linebacker Ben Niemann to their 90-man roster. As of now, there is no notice of a corresponding move.
Niemann is a six-year NFL veteran who has started 21 career games. Initially undrafted out of Iowa, he spent the first four years of his career with the Kansas City Chiefs, making 62 game appearances over that time and winning a Super Bowl. While he saw plenty of time on defense, his major role was on special teams, where he logged at least 240 snaps in each of his first four seasons.
