Linebacker Desmond Bishop will visit the 49ers on Monday, according to csnbayarea.com.
Bishop played in two games for the 49ers last season after beginning the year with the Cardinals. After losing both Patrick Willis and Chris Borland to retirement, the team is looking for linebackers.
Over his eight-year NFL career, the 30-year-old has 299 total tackles, nine sacks, nine passes defensed, one interception and eight forced fumbles.
