The 49ers have shuffled the bottom of the roster, with three pairs of transactions.
Lauderdale has been on their practice squad and with them in the 2017 and 2018 offseasons. He has also spent time with the Bills, Cardinals, and Jaguars. Robinson was on their 53-man roster the last three weeks of last season, but was inactive for all three games. This is Thompson’s second stint with the 49ers this offseason.
Poindexter was lost to a torn ACL in Monday’s preseason game.
