The 49ers made a roster move today, releasing former Stanford center Chase Beeler and re-signing former Stanford defensive lineman Matt Masifilo, who was cut on Monday. The team may have found itself light along the defensive line after Demarcus Dobbs' recent injury -- he was on crutches this week -- and after cutting Masifilo and fellow undrafted rookie Patrick Butrym.
The starting units are not expected to play long in Thursday's preseason finale and there likely is a reluctance to expose starters and key backups to injury. Behind starters Justin Smith, Isaac Sopoaga and Ray McDonald are Ricky Jean Francois, Will Tukuafu, Dobbs, Ian Williams and Tony Jerod-Eddie.
The 49ers also released center Jason Slowey on Monday. Daniel Kilgore is the No. 2 center behind Jonathan Goodwin; Derek Hall also played some center this offseason.
