The Denver Broncos will have a completely new quarterbacking crew in the first year of the Josh McDaniels era.
Denver cut quarterback Darrell Hackney on Monday. He had been a backup and practice squad player for Denver. His release comes four days after Denver traded Pro Bowl quarterback Jay Cutler to Chicago. Cutler's primary backup, Patrick Ramsey, signed with Tennessee last week after Denver did not pursue bringing him back.
Meanwhile, Oakland has signed offensive lineman Marcus Johnson. He was with Minnesota. Johnson was a second-round pick in 2005 and has played sparingly the past two seasons.
He will likely compete to make Oakland's roster. He can play both tackle and guard. His signing will likely not alter Oakland's plans to draft an offensive lineman. Oakland has also signed tackle Khalif Barnes and traded for center Samson Satele this offseason.
