The Rams are set to sign wide receiver Nick Williams, according to Mike Garafolo of NFL.com (on Twitter). Williams, a former UDFA of the Redskins, has history with coach Sean McVay and could contribute quickly thanks to his familiarity with the offensive system. 
Cooper Kupp is expected to miss at least one game, so the Rams were in need of support. If Williams is on the active roster, he’ll have an opportunity to contribute this Sunday against the 49ers.
Williams appeared in two games for the Titans this season, but was let go earlier this month after dropping a would-be go-ahead touchdown pass against the Bills. It was a bad play for the 27-year-old (28 in November) and he’ll seek redemption in Los Angeles.
The 6-0 Rams will rely on Brandin Cooks and Robert Woods as their top receivers while Kupp is out, but Williams will be among the depth options on hand.
