The Raiders have signed defensive lineman Ethan Westbrooks, according to a team announcement. In related moves, they have waived defensive lineman Ronald Ollie and tight end Erik Swoope. 
Westbrooks spent his first five years with the Rams and started in nine contests for L.A. in 2017. In that season, he registered four sacks, marking a new career high.
Last year, however, was not his finest. In September, Westbrooks was cuffed for possession of a stolen handgun. He still appeared in all 16 games for the Rams, but he made zero starts for their star-studded front seven and finished out with just eight tackles and one sack. With the Raiders, he’ll likely find himself as a depth addition once again.
Swoope, a former basketball standout at the University of Miami, had a noteworthy year with the Colts in 2016. Thanks in part to injury, he has yet to see similar playing time since then or match his average of 19.8 yards per reception (across a limited sample of 15 catches).
