Micah Parsons' back issue might be something after all.While some viewed his "back tightness" designation at Dallas Cowboys camp as a way to mask the fact he didnt have his desired long-term contract extension, the newest Green Bay Packers edge rusher reportedly might need an epidural to play this Sunday in his team debut against the Detroit Lions.Parsons is reportedly dealing with an L4/L5 facet joint sprain in his back, per ESPN, which could require an injection to play.The report adds that Parsons was prescribed a "five-day course of prednisone," which is an anti-inflammatory agent used to help with back tightness. He was also on a physical therapy program with the Cowboys until he was dealt this past Thursday for two first-round picks and All-Pro defensive tackle Kenny Clark.CLICK HERE FOR MORE SPORTS COVERAGE ON FOXNEWS.COMParsons, though, was seen at Packers practice on Monday, which was his first time participating anywhere this preseason after sitting out during his contract saga in Dallas.Parsons was considered a limited participant.DAK PRESCOTT REACTS TO MICAH PARSONS TRADE TO PACKERS: 'I WASNT SURPRISED'So, given Parsons status, its not entirely certain he will be available for his new team to start the 2025 NFL season.The Packers swooped in with an offer Cowboys owner Jerry Jones liked, and they got the deal that shocked the football world done on Thursday morning. While Jones defended trading away the four-time Pro Bowler and two-time All-Pro edge rusher, the Packers made him the highest-paid non-quarterback in league history with a four-year, $188 million contract.Parsons $47 million per year on that deal blows the previous league-record deals given to Cleveland Browns star Myles Garrett ($40 million) and Pittsburgh Steelers stud T.J. Watt ($41 million) earlier this offseason.Parsons arrival in Green Bay has his new teammates giddy to see what he can add to their defense. Left tackle Rasheed Walker, who was a Penn State teammate of Parsons during their college days, even believes the move has them Super Bowl bound."I think it upped our chances by a lot," he said Monday, per ESPN. "We got a solid pass rush across the whole line. I dont think no ones gonna be able to throw the ball like that on us. Its gonna open up opportunities for our DBs and our offense, so yeah, I feel like Micahs gonna have a good presence on the field and its gonna really be advantageous to us."The key is having Parsons available on the field. Its early in the first game week of the season, but Parsons situation is worth monitoring as the week gets closer to the weekend and a highly anticipated debut for the newest Packers star.Follow Fox News Digitalssports coverage on X, and subscribe tothe Fox News Sports Huddle newsletter.
