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, who likely suffered a torn ACL in the 49ers' preseason game Monday.

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.
Robinson signed with the 49ers on Dec. 11, 2018 but he was inactive for the final three games of the season. He was waived Aug. 10. The San Diego native played his college ball at the University of Oregon.
Thompson previously signed with the 49ers Aug. 3, but he was waived Aug. 9. In 2017, Thompson appeared in 13 games for the Houston Texans, catching five passes for 84 yards.
