Denver Broncos Pro Bowl left tackle Ryan Clady reportedly tore his left ACL in practice yesterday and is expected to miss the entire 2015 season, according to ESPN.

Clady was attended to by trainers after going down on the practice field before standing up. He did not participate in the rest of practice, but he did remain on the field with a slight limp. Denver invested a second-round pick into Colorado State offensive tackle Ty Sambrailo this year, but the team will likely look to the free agent market for another healthy body at the position as well.

Clady, Denver's first-round pick in 2008, missed 14 games in 2013 due to injury. Quarterback Peyton Manning will once again have to get by without his best offensive lineman this year. That will be problematic as Denver's offensive line was its biggest weakness coming into 2015.
