Steelers release Simmons, Humpal

Posted by ESPN.com's James Walker

The Pittsburgh Steelers made a somewhat surprising move Thursday evening by releasing offensive guard Kendall Simmons. The seven-year veteran was penciled in as a potential starter for the reigning Super Bowl champions next season.

Simmons suffered an Achilles injury that kept him out of 12 games last year, so it is possible the team wasn't optimistic about his recovery for next season. Before then, Simmons was durable as he held a streak of 30 consecutive starts prior to the injury.

Pittsburgh also released 2008 draft pick Mike Humpal. The linebacker was a sixth-round pick.
