Ryland will remain Arizona's kicker for Saturday's game against the Rams with the Cardinals ruling Matt Prater (knee) out for the contest.

Prater took part in practices for the second week in a row after having his 21-day evaluation window opened Dec. 18, but since the 40-year-old has yet to upgrade to full participation, the Cardinals are opting to keep him on injured reserve for at least one more game. His continued absence sets the stage for Ryland to once again handle kicking duties for Arizona. Ryland is coming off a 12-point performance in the Week 16 loss to the Panthers that was highlighted by a game-tying 58-yard field goal that sent the game to overtime.

Prater (knee) has been ruled out for Saturday's game at the Rams, Theo Mackie of The Arizona Republic reports.

Since the Cardinals designated him for return from injured reserve last Wednesday, Dec. 18, Prater has been listed as limited on all six of the Cardinals' practice reports. On both occasions, he didn't progress enough to be given a chance to play Weeks 16 or 17, giving him only one more opportunity to kick again this season Week 18 against the 49ers. Chad Ryland will continue to serve as Arizona's placekicker this weekend.

Folk (abdomen) didn't practice Thursday, Jim Wyatt of the Titans' official site reports.

Folk's abdominal injury prevented him from playing in the Titans' 38-30 loss to the Colts in Week 16 and has now kept him sidelined for the team's first two Week 17 practices. According to Terry McCormick of TitanInsider.com, the Titans remain hopeful that Folk will be able to handle kicking duties in this Sunday's game in Jacksonville, but Tennessee added some insurance by signing Matthew Wright to their practice squad Thursday. Wright would presumably be elevated to the roster Saturday if Folk is in any danger of missing a second straight game.

Butker converted on his lone field-goal attempt and went 2-for-3 on his extra-point tries during the Chiefs' 29-10 win over the Steelers on Wednesday.

Butker missed his first extra-point attempt of the game early in the first quarter, but it was a more difficult kick due to Xavier Worthy picking up a 15-yard unsportsmanlike conduct penalty after catching a seven-yard touchdown pass from Patrick Mahomes. Butker had no problem connecting on his next two extra-point tries and nailed a 32-yard field goal early in the third quarter to give the Chiefs a nine-point lead. In the three games since returning from injured reserve, Butker has gone 3-for-4 on field-goal attempts and 8-for-9 on extra-point tries. Butker will likely have less scoring opportunities in Week 18 against the Broncos as the Chiefs figure to rest their starters after securing the No. 1 seed in the AFC with their win on Christmas Day.

Tucker converted on his lone field-goal attempt and all four of his extra-point tries during the Ravens' 31-2 win over the Texans on Wednesday.

Tucker nailed a 52-yard field goal late in the first quarter to give the Ravens a 10-0 lead. The All-Pro kicker has been uncharacteristically innaccurate this season, converting on just 73.3 percent of his field-goal attempts. However, he hasn't missed a kick since the Ravens' Week 14 bye, going 3-for-3 on field-goal tries and 13-for-13 on his extra-point attempts over Baltimore's last three games. Tucker will look to finish the regular season strong against the Browns in Week 18.

Boswell converted his lone field-goal attempt while making his lone extra-point try during Wednesday's 29-10 loss to Kansas City.

Boswell remained perfect for a fourth consecutive week Wednesday, but he didn't see many opportunities as the Steelers' offense struggled to generate much offensive production. Heading into next week's regular-season finale against the Bengals, Boswell has converted 40 of 43 field-goal attempts while making all 33 of his extra-point tries this year.

The Titans signed Wright to their practice squad Thursday, Jim Wyatt of the team's official site reports.

Wright arrives in Tennessee having previously appeared in three games between stops with the 49ers and Chiefs, during which he converted on 11 of 12 field-goal attempts and five of five extra-point tries. He'll give Tennessee another option at kicker after the team waived Brayden Narveson, who filled in for an injured Nick Folk (abdomen) in Week 16 and hit both of his extra-point tries but misfired on his lone field-goal attempt in a 38-30 loss to the Colts. Wright will likely be elevated to the active roster and serve as the Titans' kicker for Sunday's game against the Jaguars if Folk isn't cleared to play.

Prater (knee) practiced in a limited fashion Wednesday, Josh Weinfuss of ESPN.com reports.

Prater now has been listed as a limited participant on five consecutive injury reports dating back to last Wednesday, but it's unclear if he needs to get back to full participation in order for the Cardinals to feel comfortable enough for him to resume kicking for the first time since undergoing meniscus surgery on his left knee in October. Arizona will need to activate him from injured reserve by 4 p.m. ET on Saturday in order for him to play later that evening versus the Rams, but if he doesn't get back on the active roster for that contest, Chad Ryland will continue to handle placekicking duties for the Cardinals.

Folk (abdomen) was listed as a non-participant in Wednesday's practice estimate, Turron Davenport of ESPN.com reports.

Folk missed the team's Week 16 loss versus the Colts with an abdomen injury and is now in danger of missing his second straight contest. If the 40-year-old ends up being unable to return for Sunday's game versus the Jaguars, Brayden Narveson will handle the kicking duties once again.

Little converted both of his extra-point attempts during the Jaguars' 19-14 loss to the Raiders this past Sunday.

Coming off a 4-for-4 performance on field-goal tries against the Jets in Week 15, Little did not attempt a field goal during this past Sunday's loss. Little has been one of the most accurate kickers in the league, converting on all 23 of his extra-point attempts and going 22-for-24 on field-goal tries. He should have more opportunities to score points Sunday against a Titans team that gave up 38 points to the Colts in Week 16.
