Looney announced his retirement from the NFL on Wednesday, Michael Elsen of the Giants' official site reports.

EDGE Analysis

Looney signed a deal with the Giants over the weekend, but he opted to retire after going through a couple days of practice. The 30-year-old appeared in 104 games (42 starts) over his nine-year career with the Cowboys, 49ers and Titans.

Looney agreed to sign with the Giants on Saturday, Mike Garafolo of NFL Network reports.

EDGE Analysis

Looney will be reuniting with Jason Garrett, who was his head coach during the majority of his tenure with Dallas. It was reported that Looney was close to signing with the Giants last year before he ultimately decided to stay with the Cowboys. The 2012 fourth-round pick is likely to compete with Brett Heggie for the backup role behind Nick Gates.

The Cowboys activated Looney (knee) from injured reserve Saturday, Adam Caplan of SiriusXM NFL Radio reports.

EDGE Analysis

Looney returned to practice Wednesday and will return to action after spending the minimum three-game stint on IR. He should start at center Sunday against the Eagles, although it's still unsettled whether he'll immediately return to his starting role or if Tyler Biadasz will retain the gig for one more week.

Looney (knee) was designated to return from injured reserve Wednesday, Rob Phillips of the Cowboys' official site reports.

EDGE Analysis

The 30-year-old is returning to practice this week and could be activated for Sunday's game at Philadelphia since he's already spent the three-game minimum on injured reserve. However, Looney may need a bit more practice time before reaching game readiness, so a return in Week 9 seems like a safer bet.

The Cowboys placed Looney (knee) on injured reserve Saturday, Jon Machota of The Athletic reports.

EDGE Analysis

Looney was handed a 2-to-3 week recovery timeline following news that he suffered a sprained MCL in Week 4, and now he'll officially be shut down until Week 8. Expect Tyler Biadasz to start at center until Looney can return.

Looney suffered a sprained MCL in Sunday's loss to the Browns and is expected to miss two to three weeks, Todd Archer of ESPN reports.

EDGE Analysis

Looney will sit out Week 5 against the Giants but could realistically return Week 6 against the Cardinals if his rehab goes welll. For the time being, Tyler Biadasz is expected to start at center.

Looney (knee) isn't expected to face a long-term absence after suffering a right knee sprain Sunday, Michael Gehlken of The Dallas Morning News reports.

EDGE Analysis

The 30-year-old could be sidelined for Week 5 due to the injury, but he may end up missing only the one contest. Rookie Tyler Biadasz lines up to start at center if/when Looney is ruled out for Sunday's matchup with the Giants.

Looney will be re-evaluated Monday after suffering a sprained right knee during Sunday's loss to the Browns, Rob Phillips of the Cowboys' official site reports.

EDGE Analysis

Monday's tests should reveal whether Looney will be forced to miss any time. Tyler Biadasz took over at center Sunday and would likely start against the Giants in Week 5 if Looney sits out.

Looney went to the locker room after suffering a right leg injury in Sunday's game against the Browns, Michael Gehlken of The Dallas Morning News reports.

EDGE Analysis

Although Looney walked off the field under his own power, the veteran left the games straight to the locker room. With Looney out, rookie Tyler Biadasz took over as the team's starting center.

Looney (ankle) returned to Sunday's game against the Seahawks, Michael Gehlken of The Dallas Morning News reports.

EDGE Analysis

Looney left the game in the first quarter, but now that he's back healthy, he'll return to his usual starting role as the team's center.
