Indianapolis quarterback Andrew Luck was a full participant in Monday's practice for the first time in two weeks, though his availability for Sunday's showdown with New England remains unknown.

Luck is still day-to-day because of a sore right shoulder and had been limited in practice since leading Indianapolis to a 35-33 win at Tennessee on Sept. 27.

"It feels better every day," Luck said. "It was good to go through practice without limitations in a sense, get out there and throw. It's feeling better."

Indy could use Luck this week when the Colts (3-2) host defending Super Bowl champion New England (4-0) on Sunday night, but the they also have found ways to win without him lately.

Backup quarterback Matt Hasselbeck threw for 213 yards and two touchdowns to lead the Colts to a 27-20 win at Houston, and he threw for 282 yards and a touchdown in a 16-13 overtime win at Jacksonville.

The two wins, both with Luck watching from the sidelines, has made the urge to play that much stronger.

"We all want to play," Luck said. "Every athlete wants to be out there playing all the time. So when you're not out there you get itching to go and there's certainly a pep in your step."

After missing the only two NFL games in his four-year career, it's still unclear what shape he is in. Practice wasn't open to the media on Monday and Luck wouldn't go into detail about what exactly he did.

"More," Luck said. "Absolutely, definitely more. It was the same sort of how we would always do on a Monday, split between Hasselbeck and I."

Colts coach Chuck Pagano didn't reveal much either and only referred to the way Luck is throwing the ball as "good."

Cardinals sign Freeney

The Cardinals reportedly signed outside linebacker Dwight Freeney to a one-year contract. The move comes after the Cardinals' top pass rusher, Alex Okafor, went down because of a calf injury in Sunday's 42-17 victory at Detroit.

The 35-year-old Freeney, a seven-time Pro Bowl player, has 111 career sacks and led the NFL with 16 sacks in 2004.

His best years came with the Indianapolis Colts from 2002 through 2012. He was with the San Diego Chargers the past two seasons.

Etc.

•Chiefs running back Jamaal Charles will miss the remainder of the season after tearing his right knee ligament in the third quarter of Sunday's loss to Chicago.

"He's obviously down, but he's positive about coming back and getting himself back," Chiefs coach Andy Reid said. "That's where his energy will be directed now - getting through the surgery and getting himself back to where he can play. And that's where it should be."

Charcandrick West and Knile Davis will share carries as Charles' replacement.

•Browns star cornerback Joe Haden likely will miss one game because of a concussion sustained during Sunday's overtime win at Baltimore.

•Jets defensive end Sheldon Richardson returned to practice after serving a four-game suspension for violating the NFL's substance abuse policy.
