Pipkins (ankle) is listed as doubtful for Sunday's game against the Chiefs, Eric Smith of the Chargers' official site reports.

Pipkins was unable to practice all week after sustaining an ankle injury during the Chargers' overtime win over the Eagles on Monday. Assuming he doesn't play in Sunday's AFC West tilt, Trevor Penning and Bobby Hart would be the top candidates to start at right tackle.

Fuaga (ankle) doesn't have an injury designation ahead of Sunday's game against the Panthers, Jeff Nowak of WWL Radio reports.

Fuaga upgraded to a full participant in Friday's practice, just in time to dodge an injury designation for Sunday's divisional clash. The Saints are out of the playoff race, but a healthy right tackle for Tyler Shough will help them try to spoil the Panthers' shot at a division title.

Conklin (concussion) has been ruled out for Sunday's game against Chicago, Mary Kay Cabot of The Cleveland Plain Dealer reports.

Conklin will miss a second consecutive game while in the league's concussion protocol. He has not progressed enough in the protocol to return to practice, which jeopardizes his chances of playing Week 16 against the Bills on Sunday, Dec. 21. KT Leveston will likely start at right tackle in Conklin's absence.

Richards (ankle) is out for Sunday's matchup against the Panthers, Ross Jackson of WWL Louisiana reports.

Richards did not practice this week ahead of the Saints' Week 15 matchup against the Panthers. The 25-year-old exited in the second half of Week 14 versus the Buccaneers. Taliese Fuaga is expected to start in his place.

Darrisaw (knee) is listed as questionable for Sunday's game against the Cowboys, Kevin Seifert of ESPN.com reports.

Darrisaw was a limited participant in Friday's practice, upgrading from the non-participant status he held earlier in the week. If the left tackle is unable to suit up for Sunday's game, Justin Skule will likely start in his stead.

Teller (calf) has been ruled out for Sunday's game against the Bears, Mary Kay Cabot of The Cleveland Plain Dealer reports.

As expected, Teller will miss a second straight game due to a calf injury, which has also prevented him from practicing. Teven Jenkins is poised to start at right guard for a second consecutive game in Teller's absence.

Blair reverted to the Falcons' practice squad Friday, per the NFL's transaction log.

The Falcons elevated Blair from the practice squad ahead of Thursday night's showdown with the Buccaneers. The wide receiver and special teamer logged three offensive snaps and five special teams snaps in the win over the division rival.

Ogunbowale is expected to be a depth option Sunday, as Woody Marks, who opened the week with a knee injury, carries no injury designation ahead of the Week 15 matchup against the Cardinals.

The week started with both Marks and Nick Chubb (ribs) as non-participants in Wednesday's practice, opening a window slightly for Ogunbowale. Since then, Marks logged a limited practice Thursday and was a full participant Friday. Chubb sat out Thursday and got on the field Friday for a limited session, which included stretching on the side and working with the training staff. Ogunbowale could steal snaps from Chubb, but it looks like Marks should be a workhorse against Arizona.

Cushenberry (foot) is questionable for Sunday's matchup against the 49ers, Jim Wyatt of the Titans' official site reports.

Cushenberry missed the past two games with a foot injury suffered in Tennessee's Week 12 loss to Seattle. The 28-year-old finished the week as a full participant, which is a positive sign for Sunday's matchup against San Francisco. If he is unable to play, Corey Levin will continue to start in his place.

Huntington (quadriceps) has been ruled out for Sunday's game against the Bears, Mary Kay Cabot of The Cleveland Plain Dealer reports.

Huntington will miss a third consecutive game due to a quadriceps injury, so Sam Kamara and Mike Hall will continue to serve as the Browns' rotational options at defensive tackle behind Shelby Harris and rookie first-rounder Mason Graham (ribs). Huntington's next chance to play is Week 16 against the Bills on Sunday, Dec. 21.
