New Orleans Saints coach Sean Payton said Monday that cornerback Jabari Greer's knee injury is "significant" but did not provide any details.
Greer was injured during Sunday's win over the San Francisco 49ers. Greer's left knee bent awkwardly as he landed after breaking up a pass in the first quarter. He was then carted off the field.
"We're just kinda keeping our fingers crossed with him," Payton said, adding that Greer was still meeting with doctors. "I spoke to him last night in the hospital.
"It's always difficult when someone like Jabari, who's been with us and been a staple of what we've done defensively, goes down with an injury like he sustained. It's a knee injury, and then I'll fill you in with the specifics (Tuesday)."
Greer has been a full-time starter since joining the team in 2009. He has one interception and 12 pass breakups this season. He broke up two passes Sunday.
Corey White replaced Greer. White intercepted a pass in the second quarter but fumbled the ball through the back of the end zone for a touchback.
Payton would not say if the team will add a free-agent cornerback to the roster. The Saints have five cornerbacks in Greer, Keenan Lewis, White, Chris Carr and Rod Sweeting.
