The sides haven't talked contract in nearly a month and "there's no acrimony" at this point, according to Schefter. If Ngata doesn't sign a new deal by Tuesday, the Ravens would have to wait until the offseason to attempt to lock him up.
Ngata was given the franchise tag this offseason to keep him off the free-agent market and is earning $12.5 million this season.
The Ravens have a strong history in keeping the first-round picks who've lived up to expectations. The team's past two franchise players -- Chris McAlister and Terrell Suggs -- both eventually signed big-money extensions.
Ngata has become one of the best defenders in the NFL, and the Ravens haven't hidden their desire to keep him. At last year's owners meetings, coach John Harbaugh said the intention is to make Ngata "a Raven forever."
