The 49ers added two defensive linemen to an already stacked front-seven in April’s NFL draft. The influx of new talent won’t stop general manager John Lynch and coach Kyle Shanahan from finding ways to improve the team’s roster, especially at a position reliant on rotation.

NFL Network’s Ian Rapoport reported Monday the 49ers are hosting former Washington defensive lineman Terrell McClain in for a free agent visit.

McClain signed a four-year, $21 million deal with Washington in 2016, but only finished one season with the team before being released late April. The 6-foot-2, 300-pound defensive lineman totaled 20 tackles and two sacks in 12 games last season.

Originally drafted in the third-round by the Panthers in 2011, McClain spent 2012 and 2013 with the Texans under defensive line coach Jeff Zgonina, who joined Shanahan’s staff with San Francisco last year.

McClain could reunite with Zgonina in Santa Clara, joining former first-round picks Arik Armstead, DeForest Buckner and Solomon Thomas on a crowded 49ers defensive line. Veteran Earl Mitchell, Sheldon Day, D.J. Jones, and rookies Kentavius Street and Jullian Taylor are also among the group.
