The Steelers on Monday confirmed WR Limas Sweed had surgery for what Mike Tomlin described as an achilles tendon injury.

There's still no official word on what exactly the injury is and how long it will take him. Ed Bouchette of the Pittsburgh Post-Gazette did a little research to determine how long Sweed might be missing.

According to emedicinehealth.com, a person with such an injury will miss four to six months of activity, however, "With motivation and rigorous physical therapy, elite athletes may return to athletics as early as 3 months after injury."

Then there's the chance the tendon is completely ruptured and that would put him down for the entire 2010 season.

Jason La Canfora of NFL Network reported on Monday the Steelers are "fearing the worst" when it comes to Sweed's future.

The Steelers are reportedly receiving word from the doctors on Sweed's status on Monday.
