Weston Richburg G

Richburg (concussion) intends to sign a five-year deal with the 49ers on Wednesday at the start of the new league year, Adam Schefter of ESPN reports.

With Andrew Norwell heading to Jacksonville, the 49ers may have viewed Richburg as the top remaining interior lineman. The 2014 second-round pick played left guard as a rookie and center the past three seasons, making 50 starts in 51 games. A concussion limited Richburg to four games last year, but the Niners apparently aren't too concerned. Jimmy Garoppolo surely appreciates the effort to upgrade a shaky offensive line.

Richburg (concussion) will miss the remainder of the 2017 season and has been placed on injured reserve, Ralph Vacchiano of SNY reports.

Richburg's absence for the remainder of the campaign means Brett Jones should start at center for the Giants the rest of the way. He will attempt to recover and return to the field for 2018.

Richburg (concussion) has been ruled out for Sunday's game against the Rams, Dan Duggan of NJ.com reports.

Since right guard Justin Pugh (back) is also sitting out, both Brett Jones and D.J. Fluker will start on the Giants' offensive front.
