Coach Dan Quinn said Friday that Koo will remain the Falcons' kicker, Vaughn McClure of ESPN.com reports.

Koo has missed three combined field-goal and extra-point tries over the last three contests, but he redeemed himself in some capacity by converting two onside kicks during Thursday's loss to the Saints. While the 25-year-old looks like he'll remain on the roster through the Week 14 game with the Panthers, he'll need to improve his accuracy to keep his spot for the remainder of the season.

The Patriots released Folk (abdomen) on Friday.

Folk is unable to kick Sunday against the Texans after undergoing an appendectomy, so the Patriots removed him from the roster entirely and replaced him with Kai Forbath. Folk isn't expected to require a lengthy recovery, so the Patriots could decide to bring him back once he's 100 percent healthy.

Koo went 2-for-3 on field-goal attempts and 0-for-1 on extra-point tries during Thursday's 26-18 loss to the Saints.

The entire NFL had succeeded on two onside kicks coming into Week 13. Koo himself converted on two straight in the waning moments of the fourth quarter Thanksgiving night -- not including a third that was erased by Falcons penalty -- though the miraculous recoveries were not enough to overcome his blunders earlier in the contest. Surely, Koo cannot solely shoulder the blame for the team's second straight defeat, but the four points he left on the board proved to be pivotal as Atlanta's late rally came up short against rival New Orleans. The 25-year-old has missed three combined field-goal and extra-point attempts over the past three weeks, as the Falcons prepare for a fourth straight divisional tilt Dec. 8, this time against the Panthers.

Lutz converted all four of his field-goal attempts and both of his extra-point attempts in the Saints' 26-18 win over the Falcons on Thursday.

Lutz was a perfect 4-for-4 on field goals for the second game this season, and he played a key role in the Saints' eight-point victory. Impressively, three of his makes were from 42, 45 and 47 yards out, while his fourth was a 22-yard chip shot. Lutz is one of the most accurate kickers in the NFL this year and remains an elite option while playing on the high-flying Saints offense.

Pineiro connected on a field goal and three extra points in the Bears' 24-20 win over the Lions on Thursday.

The biggest takeaway for Pineiro was that the Bears chose to pass up a 49-yard field-goal attempt in a domed stadium in order to let the offense try to convert a 4th-and-6, showing a lack of confidence in the kicker. With a total of 19 points over his last five games, Pineiro is not a recommended fantasy option.

Folk (appendectomy) will not be available for Sunday night's game against the Texans, ESPN's Mike Reiss reports.

While Folk won't be able to kick this weekend, his absence is not expected to be a lengthy one. Per Reiss, the Patriots must now decide whether to sign another kicker in advance of Week 13 action, or alternatively, employ punter Jake Bailey as a short-term replacement for Folk.

Folk recently underwent an appendectomy that is expected to sideline him Sunday against the Texans, Ian Rapoport of NFL Network reports.

We'll await official confirmation from the team, while Rapoport notes that Folk's expected absence isn't likely to be lengthy, given that his procedure was reportedly minimally invasive. Either way, it looks like the Patriots will be on to their fourth kicker of the season when they face Houston on Sunday.

Elliott agreed Wednesday with the Eagles on a five-year, $21.8 million contract extension, Ian Rapoport of NFL Network reports.

Elliott's extension includes $10.45 million in guarantees, making him the third-highest-paid kicker in the NFL. The third-year pro has converted all 14 of his field-goal tries through 11 contests year, though he's misfired on two of his 23 extra-point tries. For his career, Elliott owns a solid 86.8 percent conversion rate from the field and has hit 93 percent of his PATs.

Tucker made his only field-goal attempt as well as all six of his extra-point tries in Monday night's 45-6 win over the Rams.

Tucker converted from 34 yards on his lone field goal, as he was otherwise limited to PAT work. Still, with Baltimore's offense consistently finding the end zone, Tucker was able to put up another strong point total, bringing his season tally to 102, ranking second league-wide.

Carlson made one of two field-goal attempts in Sunday's 34-3 loss to the Jets.

The Raiders' offense was stuffed all game long in what became a huge blowout throughout the third quarter, but Carlson failed to capitalize on a 43-yard attempt that would've given him six points on the day. He's now 11 of 15 on field-goal attempts this season as the Raiders head to Kansas City for a divisional Week 13 tilt.
