The Broncos cut Keene from their practice squad Tuesday, Aaron Wilson of ProFootballNetwork.com reports.
Keene's stint with Denver's practice squad lasted all but three days, as he was signed Saturday and let go Tuesday. The 251-pounder has six games under his belt with the Patriots in 2020, where he caught three passes for 16 yards in that span. Keene will now look elsewhere to rejuvenate his NFL career.
