The preseason roster moves never stop.
On Wednesday, the 49ers announced the addition of three players to their preseason roster.
The team signed offensive lineman Andrew Lauderdale, safety Tyree Robinson and wide receiver Chris Thompson to one-year deals. In corresponding moves, the 49ers waived offensive lineman Christian DiLauro, running back Brandon Wilds and waived/injured wide receiver Shawn Poindexter.
Lauderdale originally signed with the 49ers as an undrafted rookie free agent in 2017. After being waived and signed to the 49ers' practice squad in 2017, Lauderdale was waived last September and caught on with the Buffalo Bills where he remained on the practice squad for the remainder of the season.
