The Athletic’s Nicki Jhabvala reported earlier that the Broncos cut two wide receivers - Isaiah McKenzie and River Cracraft.
The Broncos are cutting WRs Isaiah McKenzie and River Cracraft, per source.— Nicki Jhabvala (@NickiJhabvala) September 1, 2018
And so far that leaves the Broncos currently with five wide receivers on the 53-man roster: Demaryius Thomas, Emmanuel Sanders, Courtland Sutton, DaeSean Hamilton and Tim Patrick.
Cracraft had a good training camp, but Patrick began to shine in the preseason.
As for McKenzie, we all know that story. He showed improvement this offseason/preseason, but the late fumble in the third preseason game likely sealed his fate.
Update - 9/2/17
McKenzie was then added back to the active roster as the Broncos moved Su'a Cravens to injured reserve. McKenzie could be an insurance policy as a return man in case Adam Jones doesn’t work out.
