Steelers RT Colon injured Achilles
Steelers right tackle Willie Colon has injured his right Achilles' tendon while working out at the team's practice complex.
If the tendon is torn, Colon is likely to require surgery that would end his season.
Director of football operations Kevin Colbert said Colon was being evaluated by the team's medical staff. Colon left the team's practice building Monday on crutches.
Colon's injury could be a major setback to the Steelers' plans to put a greater emphasis on the run this season. They have little depth at tackle behind starters Max Starks and Colon.
Colon is the only Steelers player who was with Ben Roethlisberger on the night the quarterback was accused of sexually assaulting a Georgia college student. Roethlisberger was not charged, but drew a six-game suspension from the NFL.
