LAKE FOREST, Ill. — With Brian Urlacher nursing a hamstring injury, the Chicago Bears on Tuesday signed Dom DeCicco to a two-year contract, adding depth at linebacker.

Urlacher's status for this week’s game at Minnesota and beyond is in question after the 34-year-old was injured on the final drive of Sunday’s overtime loss to Seattle. Coach Lovie Smith indicated Monday that he has a pulled hamstring.

The Chicago Tribune, citing sources, reported Tuesday that he is expected to miss three games and possibly the rest of the regular season. The team declined comment.

Nick Roach would likely move to middle linebacker with Geno Hayes taking his spot at strong side linebacker without Urlacher.

DeCicco appeared in all 16 games for the Bears last season. Chicago also waived/injured linebacker Patrick Trahan.

Starr has spell

Hall of Fame quarterback Bart Starr, 78, collapsed during a speech in Madison, Wis., on Tuesday. Conference organizers say he appears to be OK.

The Green Bay Packers’ former quarterback and coach finished speaking at the Wisconsin Housing and Economic Development Authority conference at Monona Terrace, then collapsed on stage.

Authority spokesman Kevin Fischer says Starr then sat up and said he was fine.

Starr led the Packers to five NFL titles and two Super Bowl championships. He was Green Bay’s coach from 1975-83.

Titans make moves

The Tennessee Titans have placed right tackle David Stewart and safety Robert Johnson on injured reserve.

The Titans filled their roster spots by adding offensive lineman Kyle DeVan and tackle Daniel Baldridge.

Stewart broke his right leg in last week’s 24-10 loss to Houston. Johnson tore ligaments in his foot.

Patriots lose Edelman

The injury list at New England continues to grow.

Rob Gronkowski broke his forearm. Chandler Jones injured his ankle. Logan Mankins hurt his hip, calf and ankle.

Now Julian Edelman is out for the season. The dangerous punt returner and elusive wide receiver was placed on injured reserve with a foot injury.

Ex-NFL star Allen dies

Grady Allen, the father of Oakland Raiders coach Dennis Allen and a former NFL linebacker, has died. He was 66.

The Raiders said that Grady Allen died overnight from cardiac arrest. Dennis Allen had left the Raiders on Sunday night to go to the Dallas area to be with his father, who was hospitalized last week.
