However, the good news for the Falcons is that this could end up costing Sanu just one game as they have their bye coming up.
Sanu, 27, is a former third-round pick of the Bengals back in 2012. He spent four years in Cincinnati before signing a five-year, $32.5 million contract that included $14 million guaranteed with the Falcons last year.
Sanu stands to make base salaries of $6 million over the next three years of the agreement.
In 2017, Sanu has appeared in four games and caught 16 passes for 163 yards and one touchdown for the Falcons. Pro Football Focus has him rated as the No. 21 receiver out of 108 qualifying players.
