How new signings Nicholas Grigsby and Jason King can help Patriots

FOXBOROUGH, Mass. -- The New England Patriots filled their two open roster spots by signing linebacker Nicholas Grigsby off the Baltimore Ravens practice squad and signing undrafted free-agent rookie offensive lineman Jason King.

King, a Purdue alum who was with the team in training camp, will help the team get through the week of practice as they have a run of injuries along the offensive line with center David Andrews (illness) and offensive tackles Marcus Cannon (ankle) and LaAdrian Waddle (ankle).

It’s possible that King might not be on the 53-man roster through Sunday’s road game against the Buffalo Bills, as the team could be buying time to assess the overall injury picture before promoting a practice-squad player to fill his spot by Saturday’s 4 p.m. ET deadline.

As for the 6-foot-2, 230-pound Grigsby, he projects to add depth on special teams with leading tackler Nate Ebner placed on injured reserve and linebacker Trevor Reilly having sustained what appeared to be a concussion in Sunday’s win over Miami.

Grigsby, who entered the NFL as an undrafted free agent out of Pittsburgh in 2016 with the Los Angeles Rams, also will add depth on defense. He played in six games last season for the Rams, one of which was against the Patriots. Grigsby played exclusively on special teams for the Rams last season.

The Patriots’ interest in Grigsby was reflected in them bringing him to town for an early September workout, shortly after he was released by the Rams.
