Former Raiders wide receiver Rod Streater is visiting the Bills today, a source tells Adam Schefter of ESPN.com (on Twitter). 
Streater, 29, spent last season with the Niners. As a member of one of the league’s worst offensive units, he caught 18 passes for 191 yards and two touchdowns.
Once upon a time, Streater appeared to be on the verge of big things with the Raiders. Unfortunately, after catching 60 passes for 888 yards in 2013, he was derailed by injuries. After appearing in just four games for Oakland between 2014 and 2015, he wound up with the Niners on a one-year deal.
Back in March, the Vikings, Colts, Seahawks, Browns, and incumbent 49ers were all said to have some degree of interest in him. For one reason or another, Streater did not sign with any of those clubs.
