NFL roundup: Rodgers confirms broken collarbone

All-Pro quarterback Aaron Rodgers is expected to be out at least a few weeks because of a broken collarbone. He confirmed the injury Tuesday afternoon during his weekly radio show on ESPN Wisconsin.

"I'm in some pain," said Rodgers, adding that a timetable for his return remains undetermined.

Rodgers sustained the injury when Chicago Bears defensive end Shea McClellin sacked him from behind and Rodgers landed hard on his left, non-throwing shoulder only 2 1/2 minutes into the Bears' 27-20 win at Lambeau Field on Monday night.

Rodgers said he won't need surgery.

A potential option to replace him became available Tuesday. Former Packers quarterback Matt Flynn, cut Monday by the Buffalo Bills, cleared waivers and is now a free agent, according to ProFootballTalk.

Since leaving Green Bay as an unrestricted free agent, Flynn was traded by the Seattle Seahawks and released by the Oakland Raiders and Bills in the past 18 months.

In other Packers news, tight end Jermichael Finley went on injured reserve due to a spinal cord contusion. Green Bay also activated tackle Derek Sherrod from the physically unable to perform list and placed linebacker Sam Barrington on injured reserve.

--Houston Texans head coach Gary Kubiak was released from a hospital Tuesday, but he is not expected to return to the team for at least one week.

Kubiak spent two nights in the hospital and a series of tests Monday determined he experienced a "mini-stroke" Sunday night.

Kubiak collapsed while jogging off the field toward the locker room at halftime during the Texans' game Sunday night against the Indianapolis Colts at Houston's Reliant Stadium.

Defensive coordinator Wade Phillips replaced Kubiak in the head coach role for the Texans and will operate in that capacity until further notice, the team confirmed.

--At the request of head coach Joe Philbin and owner Stephen Ross, the NFL opened its investigation into alleged misconduct by Jonathan Martin's teammates with the Miami Dolphins.

The NFL Players Association remains an interested observer in the investigation, the organization announced in a statement.

Martin, a second-year offensive tackle, turned over evidence to his family and representatives Sunday. The NFL also received and reviewed multiple text and voicemail messages from teammate Richie Incognito, NFL Network reported. Incognito was suspended indefinitely Sunday, not long after Philbin said he first learned of the misconduct allegations from Martin's agent.

Martin left the team last week after an incident, initially portrayed as a prank, in the team cafeteria led to an emotional breakdown.

--Chicago Bears quarterback Jay Cutler, who missed Monday's game against the Green Bay Packers due to a groin tear, aims to be available to face the Detroit Lions on Sunday, according to an ESPN report. The Bears would not confirm the report.

The team doesn't have a full practice scheduled until Thursday due to the Monday night game.

--Defensive end DeMarcus Ware is ready to return from a quadriceps injury, just in time for the Dallas Cowboys' game Sunday night at New Orleans.

Ware missed the past three games as opposing quarterbacks pile up record numbers against the Cowboys' lackluster defense. Quarterbacks are averaging 305.2 passing yards per game, completing 63.5 percent of their passes with 16 touchdowns.

The Cowboys also waived-injured defensive tackle Marvin Austin, who missed Sunday's game against the Minnesota Vikings with a back injury.

--Defensive tackle Kheeston Randall signed with the Cincinnati Bengals.

The second-year player out of Texas takes the roster spot of Geno Atkins, the All-Pro who was placed on injured reserve Monday with a season-ending knee injury.

--San Francisco 49ers wide receiver Michael Crabtree was cleared to practice for the first time since suffering a torn Achilles tendon during offseason workouts.

The fifth-year wideout is currently on the physically unable to perform list, and the team now has a 21-day window to evaluate whether to activate Crabtree or place him on season-ending injured reserve.

--The Denver Broncos activated center J.D. Walton and placed guard John Moffitt on the reserve/left squad list for not reporting from the bye week, the team announced. Moffitt later said he decided to quit playing football.

Moffitt, 27, told Sports Radio 950 KJR that he is giving up football and that he already informed the Broncos he was calling it a career.

--New England Patriots wide receiver Austin Collie was released, and the team signed former Baltimore Ravens wide receiver LaQuan Williams.

Collie was signed last month and appeared in four games for the Patriots, catching three passes for 34 yards. He left Sunday's game against the Pittsburgh Steelers after suffering a knee injury.

--The Carolina Panthers signed free agent guard/center Geoff Hangartner, the team announced. Backup offensive lineman Jeff Byers was placed on injured reserve with a foot injury. Byers underwent season-ending Lisfranc surgery on his left foot Monday.

--The Kansas City Chiefs activated defensive back Sanders Commings from injured reserve and waived safety Bradley McDougald, the team announced.

Commings, a fifth-round pick from Georgia this year, broke his collarbone at the team's first practice of training camp.

--The Pittsburgh Steelers signed cornerback DeMarcus Van Dyke and released cornerback Isaiah Green, the team announced.

--The Bears placed wide receiver Joe Anderson on injured reserve with an abdominal and groin injury, the team announced. Anderson, 24, appeared in six games this season and made one special teams tackle.
