The Bengals offense was stripped for parts this offseason, losing receivers Mohamed Sanu and Marvin Jones to the Falcons and Lions, respectively.
Cincinnati is also at risk of seeing star tight end Tyler Eifert miss games as he is recovering from ankle surgery.
With only Brandon LaFell behind A.J. Green, Bengals director of player personnel Duke Tobin addressed the possibility of free-agent receiver Anquan Boldin.
"I don't like to proclaim 'yes' or 'no' on anybody that's out there, but we have not had any discussions with (Boldin)," Tobin told the Bengals' official website.
"We feel pretty good about some young guys that we have in that position group. It's a position group that's in flux, and it's a position group that's going to have to step up - particularly with Eifert out early in the year."
The Bengals in the second round of the 2016 NFL Draft added wideout Tyler Boyd, a 6-foot-1 pass catcher out of Pitt.
Boldin, who turns 36 years old in October, played his last three seasons for the 49ers, breaking 1,000 yards in two of them.
His 789 receiving yards and 11.4 yards per reception in 2015 marked his lowest totals since his sophomore season in 2004 with the Cardinals.
