San Francisco 49ers wide receiver Brandon Aiyuk is not expected to play Thursday night against the New York Giants because of a shoulder injury, a league source told ESPN's Adam Schefter.
Aiyuk is listed as questionable for the game.
The 49ers announced Thursday they have elevated receiver Chris Conley from the practice squad for the game.
Aiyuk suffered the injury on his first catch in Sunday's game against the Los Angeles Rams, a 30-23 49ers victory. He finished the game with three catches for 43 yards.
