DETROIT -- Jordon Dizon is scheduled to undergo an MRI exam on his injured left knee today, and regardless of the results the Lions could be looking for linebacker help in free agency.

Dizon, a former Colorado standout, was injured in the second quarter of Saturday's 23-7 exhibition loss to the Steelers. He left Heinz Field on crutches and with a heavy brace protecting his knee.

Coach Jim Schwartz said after the game Dizon's injury "looked pretty significant."

"If the knee injury's what we think it is, we'll probably be making a move there," Schwartz said.

With DeAndre Levy nursing a back injury, Dizon started at middle linebacker against the Steelers. He was expected to be a key backup and special-teams contributor for the Lions this year.

Levy hasn't practiced in almost two weeks, and if he doesn't return today the Lions will be down to seven healthy linebackers for their afternoon workout.

If Dizon misses the season as expected, Vinny Ciurciu would be Levy's primary backup at middle linebacker. Ciurciu made a team-high five tackles Saturday.

Two free-agent linebackers who might interest the Lions are Rocky Boiman and Ryan Stamper. Boiman, who played under Schwartz in Tennessee in 2002-05, worked out for the team earlier this summer.

Stamper agreed to a contract with the Lions as an undrafted free agent, but failed his physical because of a back injury.

Garriet Blair, Stamper's agent, said Sunday he still expects his client to sign with the Lions, possibly as early as this week. Blair said Stamper and the Lions were close to reuniting before Dizon's injury.

"I don't have any idea what's transpiring with (Dizon). I just know where things stood with Ryan," Blair said. "I'll be surprised if he wasn't back up there this week."
