Sources: Niners, Aiyuk reach $120M extension

The 49ers and wide receiver Brandon Aiyuk reached agreement Thursday on a four-year, $120 million extension that will contractually tie him to San Francisco for the next five seasons, sources told ESPN's Adam Schefter.

Aiyuk joins Miami Dolphins star Tyreek Hill as the fifth-highest paid receiver with an average annual value of $30 million per season.

Aiyuk, 26, had 75 catches for 1,342 yards and seven touchdowns for the Niners last season.
