Alvin Kamara is a unit and the running back is one of the most crucial members of the New Orleans Saints offense. Kamara is a persistent red zone threat, and it takes genuine effort and skill for a defense to keep him quiet throughout a game.Before Week 15, let's look at the Saints star's availability.Is Alvin Kamara injured?No, Alvin Kamara is not injured. However, the New Orleans Saints RB1 is dealing with an undisclosed illness ahead of his side's Week 15 game against the Washington Commanders.The illness has caused Kamara to miss the first two training sessions of the week. Given the importance of the game against the Washington Commanders, Kamara's absence might concern Saints' fans and his fantasy managers.Kamara is not the only Saints member currently missing training sessions. Quarterback Derek Carr (hand), linebacker D'Marco Jackson (ankle) and wide receiver Bub Means (ankle) have not participated in this week's training.How has Alvin Kamara performed in 2024?Kamara has been a bright spot in a difficult season for the New Orleans Saints. The running back is playing some of the best football of his career on the rush-heavy Saints and he's currently on track to record his first season with 1,000 rushing yards.Kamara has racked up a stat line of 223 carries, 938 rushing yards and six touchdowns in 13 games. He has also added 485 receiving yards and a touchdown for good measure. He ranks fifth in carries and eighth in rushing yards for the 2024 season.The New Orleans Saints will hope that Kamara features in Week 15, as their playoff hopes are dwindling. They have a 5-8 record and are behind the Tampa Bay Buccaneers and Atlanta Falcons in the divisional standings. One more loss this season will guarantee a losing record, and teams with losing records hardly ever make the playoffs.
