Palmer recorded one tackle in his first game with Tennessee.
After spending his first three seasons with the Packers, Palmer joined the Titans during the offseason. He's a backup linebacker who didn't see a single defensive snap Week 1, recording his one tackle on special teams. It's unlikely he has any value in IDP leagues this season.
Riggs appeared in 11 games for Tennessee as a rookie last season, but the 24-year-old struggled to produce while on the field. The Titans were able activate Riggs to the 53-man roster by parting ways with quarterback Alex Tanney. Although he may serve as a contributor on special teams, it appears that Riggs will function as a last resort option in the Tennessee secondary.
Walker (hamstring) is listed as questionable for Sunday's game against the Texans.
Walker, who missed last Sunday's game due to a hamstring problem, was limited in practice both Thursday and Friday. Although Walker believes his odds of returning for Week 4 are improving, his status will still need to be checked prior to the Titans' 1:00 ET kickoff. If Walker is unable to play, Jace Amaro, Anthony Fasano and Phillip Supernaw would be left to fill the void at tight end.
Hill (ankle) has been ruled out for Sunday's game in San Diego.
With Hill missing a third straight game, Coby Fleener once again has virtually no competition for snaps. Unless he gets healthy and Fleener heads in the other direction, Hill won't have much of a role in the New Orleans offense.
Laurinaitis had seven tackles (five solo) in Monday night's loss to the Falcons.
The Falcons ran the ball 31 times, compared to only 30 passes, which gave the veteran middle linebacker plenty of opportunities to make stops. In his first three games, Laurinaitis now has 17 total tackles, including seven tackles each in Weeks 1 and 3. Playing at the heart of the Saints' defense, Laurinaitis should continue to be a solid IDP option.
Snead (toe) is listed as questionable for Sunday's game in San Diego.
According to NOLA.com, Snead is highly optimistic about his chances to play, saying he feels much better than he did prior to Monday's game against Atlanta. While he's trending in the right direction, owners will still want to have another option available from either the late-afternoon games or the Sunday or Monday night contests, as Snead was a limited practice participant all week. The Saints and Chargers will kick-off at 4:25 P.M. ET.
Vaccaro (ankle) expects to play in Sunday's matchup with the Chargers, The Times-Picayune reports.
Vaccaro injured his ankle in Week 2's loss to the Giants, and subsequently missed the following game. He indicated his absence was more of a coaching decision, as he felt he could have played through it. The starting strong safety appears to be on track for a return Sunday.
The Saints released Brown (calf) with an injury settlement Thursday, removing him from injured reserve, the New Orleans Times-Picayune reports.
Brown joined the Saints in May, adding a veteran presence to a receiving corps lacking in experience. However, he failed his pre-training camp physical due to a strained calf, which will bring his brief tenure in New Orleans to a close. The severity of the injury will likely determine when he receives a chance with another organization.
