Clelin Ferrell didn't give up and he was rewarded with his first career NFL sack.
Midway through the fourth quarter Monday night, Broncos quarterback Joe Flacco dropped back but couldn't find an open receiver.
Ferrell kept pushing and ended up sacking Flacco. He got a little help from P.J. Hall, but the No. 4 overall draft pick was credited with the sack.
Most analysts felt the Raiders reached for Ferrell at No. 4, but coach Jon Gruden and general manager Mike Mayock defended their selection.
In his NFL debut, Ferrell held his own and made the Raiders brain trust look smart.
