Packers wide receiver Allen Lazard is out indefinitely after undergoing core muscle surgery, as ESPN.com’s Adam Schefter tweets. The timing is unfortunate as Lazard is coming off of one of the best games of his career — a six-catch, 146-yard showing against the Saints. The Packers placed Lazard on IR Saturday.

The Packers could now be without their top two receivers heading into Monday’s game against the Falcons. Davante Adams remains questionable with a hamstring injury, which could leave Green Bay with Marquez Valdes-Scantling, Malik Taylor, and recent practice squad call-up Darrius Shepherd as their only three receivers. At minimum, you can expect the Packers to add one receiver to the group over the weekend, possibly Robert Foster, Caleb Scott, or Juwann Winfree from their expanded 16-man unit.

So far, Aaron Rodgers has loved what he’s seen from the 24-year-old former UDFA. Unfortunately, he’ll have to wait a while before he gets to work with him again.

“He was as productive as just about anybody in camp, and I really like his approach,” Rodgers said (via ESPN.com). “He’s the one who’s always in Davante’s ear, listening to what he’s talking about. Damn near every time I come in the Hutson Center during training camp when we’re starting practice, I walk in and do the same thing, put my helmet down. And Shep is picking Davante’s brain about releases and certain things. And look, I try and pay attention as much as I possibly can, but that sticks with you. That impacts you. You’re seeing just that desire to improve and get better. And then you see it on the field.”
