Remember M.D. Jennings? The last time the Seahawks saw him in the regular season, he was trying to pick off the infamous “Fail Mary” pass.

Until this week, that is. According to NBC’s Pro Football Talk, Seattle tried out the former Green Bay Packers free safety on Tuesday as the Seahawks ostensibly search for more depth in the defensive backfield.

Jennings, 26, played for the Chicago Bears this preseason but hasn’t yet found a new home in the NFL after three years with the Packers. Last season, he started all 16 games for Green Bay, picking up 77 combined tackles, a sack and a fumble recovery for a touchdown.

Over his three years in the NFL, the undrafted Arkansas State alumnus has started 26 of 47 games and has 124 total tackles to go along with one interception. But he could have had two interceptions in 2012 if things went his way when the Packers visited Seattle that Sept. 24.

It was two years ago Wednesday that he tangled with former Seahawks receiver Golden Tate while going up for quarterback Russell Wilson’s Hail Mary pass on the final play of the “Monday Night Football” matchup. While Jennings appeared to intercept the ball, which would have given Green Bay a 12-7 victory, the NFL’s replacement officials said Tate had simultaneous possession and signaled a Seahawks touchdown.

Seattle wound up winning 14-12, much to the ire of football fans around the nation. The controversy over Tate’s “Fail Mary” catch effectively ended the NFL’s labor lockout with its regular officials — not to mention an outpouring of hatred and threats toward the replacement side judge who called the TD, Lance Easley.

Oh, what the NFL would give to be mired in such a relatively benign controversy … but we digress.

The 2014 Seahawks, now with a Lombardi Trophy in hand, are missing a few pieces in its vaunted Legion of Boom secondary. With cornerbacks Brandon Browner and Walter Thurmond now gone, Seattle planned to rely on Byron Maxwell, Jeremy Lane and Tharold Simon alongside starters Richard Sherman, Earl Thomas and Kam Chancellor.

Yet Lane is sidelined at least six more weeks with a groin injury and Simon is working to return from minor knee surgery, leaving newcomers Marcus Burley and Josh Thomas to provide depth at third and fourth cornerback despite joining the team just before the regular-season opener. Backup cornerback DeShawn Shead has the ability to also play safety, but Earl Thomas is the only player designated as a free safety on Seattle’s roster.
