The Baltimore Ravens are doing a whole lot of talking ahead of their Week 9 showdown with the New England Patriots, but their chances of winning may have just taken a major hit.

According to Josh Alper of Pro Football Talk, Ravens safety Earl Thomas did not practice on Wednesday due to a knee injury.

Not much is known about the severity of the injury, but obviously, it was concerning enough for Baltimore to hold him out of its practice session, and if he is unable to go against the Patriots on Sunday, it will certainly leave the Ravens with a big hole in their secondary.

Thomas signed a lucrative four-year deal with Baltimore back in March. Through seven games, he has logged 24 tackles and an interception.

The 30-year-old, who played his collegiate football at the University of Texas, was originally selected by the Seattle Seahawks in the first round (14th pick overall) of the 2010 NFL Draft.

It didn't take Thomas long to stamp his name among the best defensive backs in the league, as he made the Pro Bowl as soon as his second season and went on to nail down five straight Pro Bowl appearances between 2011 and 2015, earning three First-Team All-Pro selections and helping the Seahawks win a Super Bowl along the way.

Thomas then made another trip to the Pro Bowl in 2017 before a broken leg injury limited him to just four games during his final season with Seattle last year.

The Ravens have gotten off to a 5-2 start and are coming off of a Week 7 win over Thomas' former Seahawks team. Baltimore had a bye in Week 8.
