FLOWERY BRANCH — The Atlanta Falcons' revamped offensive line took a major setback Sunday when left tackle Sam Baker was ruled out for the year after injuring his right knee in a preseason game. The Falcons said the injury plagued Baker sustained a torn patellar tendon in a 32-7 loss to the Houston Texans on Saturday night. First-round pick Jake Matthews could move from right to left tackle to replace Baker, but the injury is a huge blow to Atlanta's efforts to bolster a line that was one of the league's worst a year ago.
