According to SI.com's Peter King, Nate Keading (ACL surgery) has a "legit challenge" from Nick Novak in training camp.

King is stationed at Chargers camp and ostensibly got the information on good authority from the coaching staff. Although Novak exceeded expectations as Kaeding's fill-in last season, his accuracy has never been in the same neighborhood. Kaeding is fully recovered and should have the edge in camp.

Chargers K Nate Kaeding is fully recovered from his torn left ACL.

The North County Times clarifies that Kaeding suffered "multiple ligament tears," so his injury appears to have been more extensive than a routine ACL. The tears happened in Kaeding's non-kicking leg. Though Nick Novak was terrific in Kaeding's stead last season, it's expected that he'll get his kicking job back.

Chargers K Nate Kaeding (ACL surgery) is ahead of schedule in his recovery and will resume kicking field goals later this month.

Kaeding, who tore the ACL in his non-kicking leg last September, recently said he "doesn't anticipate a camp competition." He's in for a rude awakening after Nick Novak nailed 27-of-34 field goals in 2011, including 15-of-16 tries within 40 yards. Kaeding is owed $2 million compared to Novak's $700K. The longtime Charger kicker's roster spot is very much in danger.

The Chargers have confirmed K Nate Kaeding is done for the season with a torn ACL in his non-kicking leg.

A perennial top-five fantasy kicker, Kaeding appears poised to be replaced by Nick Novak, who is just 19-of-30 lifetime on field goals. You should be able to do better for a replacement, though Novak could rack up points in San Diego's elite offense. He just won't be a good bet to keep the job for long.

NFL Network's Jason La Canfora reports initial indications are that Chargers K Nate Kaeding has a torn left ACL.

The Bolts scheduled Kaeding for a Monday MRI, but "they are not hopeful," per La Canfora. ESPN's Adam Schefter has since confirmed the report. Look for Kaeding to be placed on season-ending injured reserve on Tuesday. A two-time Pro Bowler, Kaeding is annually one of the most productive kickers in the NFL.

Per the San Diego Union-Tribune, it would take a "miracle" for Chargers K Nate Kaeding (knee) to play in Week 2.

The Chargers aren't considering placing Kaeding on I.R. yet, but he's going to have to be dropped in fantasy leagues with a multi-week injury. Kaeding got hurt on Percy Harvin's 103-yard kickoff return Sunday -- the first play of the game. The Chargers will have to sign a kicker off the street.

Chargers K Nate Kaeding was carted to the locker room with an undisclosed injury early in Sunday's game against the Vikings.

Nate Kaeding went 5-for-5 on field goals Sunday night even though he said his groin injury is not yet back to 100 percent.

Kaeding is not at full strength, but he looked just fine on both field goals and kickoffs against the Chargers. He's the league's best kicker when healthy, so no one should be surprised. Still, Kaeding remains a fantasy risk due to the possibility of in-game injury.

Nate Kaeding (probable, groin) practiced fully all week, and is expected to be ready for Monday Night against Denver.

We have Kaeding ranked as Week 11's No. 17 kicker in a matchup with enough offensive firepower to turn into a shootout. Fill-in kicker Kris Brown remains on the roster for insurance purposes in case Kaeding aggravates his injury. Consider the former Hawkeye as a sneaky upside pickup to have in your back pocket for Monday Night.

Nate Kaeding (groin) remains on track to handle kicking duties Monday night against the Broncos.

Kris Brown is still on the roster, but the Chargers are expected to release him by the weekend. Keading is just 27th this year in fantasy points per week among kickers.

Nate Kaeding (groin) has resumed kicking during the Chargers' Week 10 bye.

Kaeding is fully expected back in Week 11 against the Broncos. The Chargers play each of their next five games either in sunny San Diego or inside a dome. Kaeding will be worth immediately plugging back into fantasy lineups.

Nate Kaeding (groin) is expected back following the Chargers' Week 10 bye.

Kris Brown has filled in well, but this is Kaeding's job. if healthy, the All-Pro will be a fantasy asset down the stretch as the Chargers figure to be in plenty of warm-weather shootouts.

Chargers K Nate Kaeding (groin) is not practicing again this week.

Kaeding is headed toward a third straight game missed due to the groin injury. Expect Kris Brown to handle field-goal duties once again in a potential shootout at Houston.

Chargers K Nate Kaeding (groin) is not expected to be available for Week 8.

Kaeding is out indefinitely after tweaking his surgically repaired groin. Kris Brown will continue to fill in.

Chargers coach Norv Turner indicated Wednesday that there's no set timetable for K Nate Kaeding (groin) to return.

Kaeding "tweaked" the same groin in Week 6 that he had surgically repaired over the offseason. "Those type of injures," Turner said, "they can come back in a couple of weeks, or he could be out until after the bye." Fantasy owners should feel confident dropping Kaeding for healthier kicker options.

Chargers K Nate Kaeding (groin) is not expected to be available for Week 7.

The Chargers will look outside the organization for a replacement against the Patriots. Matt Stover and John Carney are two free agents that come to mind.

Chargers K Nate Kaeding is once again dealing with a nagging groin injury.

Kaeding underwent surgery to correct the problem during the offseason, but he "tweaked" the groin before Sunday's game. Punter Mike Scifres handled kickoffs, and Kaeding blew a potential tying field goal when he slipped as he planted late in the game. "It was a fight throughout the game," Kaeding said. The Chargers may have to add another kicker.

Chargers K Nick Kaeding has consulted with a sports psychologist "about six" times since he missed three field goals in the playoff loss to the Jets.

Kaeding has psychologists before, so this is nothing new. Still, six sessions suggest that a serious mental block remains. As one of the most accurate kickers in history, Kaeding's job is safe for now. Another disastrous playoff performance could have the Bolts looking for other options next offseason, though.

Nate Kaeding has resumed kicking at Chargers Organized Team Activities.

Kaeding, who had surgery on his groin after apparently tearing it in the Pro Bowl, tied David Akers for the NFL lead with 32 made field goals last season. No AFC kicker had a better field goal percentage, earning him All-Pro honors.

Nate Kaeding (groin surgery) said he recently began some light kicking.

Kaeding is not attending the Chargers' OTA this week and added that the injury occurred during the Pro Bowl. That means his groin wasn't an issue when he missed three field goals against the Jets in the playoffs. Still, as long as Kaeding proves he's healthy in training camp, we'd consider him an elite fantasy option. He led the all kickers in points last season by making 32-of-35 field goals.
