Johnson (undisclosed) was placed on the PUP list Sunday, Vincent Bonsignore of the Las Vegas Review-Journal reports.
Johnson was apparently dealing with an injury during OTAs and will now start training camp on the PUP list. Last year, the 2019 fourth-round pick appeared in 14 games for Las Vegas and registered 13 tackles. The Houston product is eligible to return from the list at any time during the preseason.
