Agent: Colon injury 'a nine-month rehab'

Pittsburgh Steelers starting right tackle Willie Colon's worst fears were confirmed Tuesday when medical tests revealed he has a ruptured right Achilles tendon. The injury will knock Colon out for the entire 2010 season.

"It's torn, and he's getting surgery [Wednesday] morning with [team physician] Dr. James Bradley," Colon's agent, Joe Linta, said. "He's expected to have a full recovery, and it's about a nine-month rehab."

Pittsburgh now has to look within the organization or sign a veteran free agent to replace Colon, who started every game for the Steelers the past three seasons.

The Steelers are beginning to address replacing Colon for this season and will bring former Cowboys offensive tackle Flozell Adams in for a visit.

Jordan Woy, Adams' agent, told ESPNDallas.com's Calvin Watkins that his client has other teams on his list, but for now the Steelers decided to take a look.

If the Steelers don't sign Adams, some internal options to replace Colon include moving offensive guard Trai Essex to right tackle, or playing backups Jonathan Scott or Tony Hills.

Levi Jones is also a free agent with starting experience that is available.
