ATLANTA — Thursday night football has become known for injuries, and the New Orleans Saints' appearance this season lived up to that reputation. 

New Orleans lost several players to injury during Thursday's game against the Atlanta Falcons. 

Rookie running back Alvin Kamara, a key weapon for the New Orleans offense this season, suffered a concussion on the first series and did not return. 

Kamara was featured heavily on the Saints' first series. He had one carry for 2 yards and caught three passes for 25 yards in the first eight plays, but he paid a price on his final catch. 

Taking a screen pass from Drew Brees in the flat, Kamara crouched down and took a helmet-to-helmet hit from former LSU linebacker Deion Jones

Kamara was evaluated in the Saints' medical tent on the sideline before heading to the locker room before the start of the offense's second series. 

But Kamara was far from the only Saint who suffered an injury. 

Rookie defensive end Trey Hendrickson, who battled a knee injury this week in practice, suffered an ankle injury late in the second quarter; he was examined on the sideline and then carted off the sideline before being declared out.

Left guard Senio Kelemete, playing in place of an injured Andrus Peat, suffered a concussion late in the second quarter and was ruled out for the rest of the game. 

Middle linebacker A.J. Klein, who was listed on the injury report with a groin injury during the week but practiced in full Wednesday, went down making a tackle and immediately headed to the locker room.

Safety Kenny Vaccaro suffered a groin injury late in the second quarter and ended up being ruled out. Vaccaro later said in the locker room that he will be fine for the game against the Jets in 10 days, but that a lack of recovery time caused an injury to his adductor muscle to flare up. 

Wide receiver Michael Thomas, tight end Josh Hill, wide receiver Ted Ginn Jr., running back Mark Ingram and defensive tackle David Onyemata to leave the game briefly, but all returned to action after being examined.
