McCourty, 31, has spent nine seasons in New England. This season his twin brother, Jason, joined him on the Patriots.
Patriots safety Devin McCourty is unsure what his future holds after his team takes on the Los Angeles Rams in Super Bowl LIII, but he has not ruled out retiring if New England wins.
In an interview with Deion Sanders on Opening Night in Atlanta, McCourty said that he "doesn't know for sure" but added that playing alongside his twin brother Jason on the Patriots this season has made it extra special.
"I don't know for sure, man. But I do look at it -- if we can win this game, winning with my brother [Jason], I don't know what else I could do that could top that," McCourty said. "So I'm just trying to make sure I enjoy this season and enjoy these last couple days with these guys."
The Patriots acquired Jason, a cornerback, from the Browns in a trade last March. After playing alongside his brother at Rutgers in college, Jason spent eight seasons in Tennessee with the Titans and then spent one year in Cleveland before rejoining Devin in New England.
Devin, 31, is in his ninth season with the Patriots. The eight-time team captain has spent his entire NFL career in New England after being taken by the Patriots in the first round of 2010 draft.
The two-time Pro Bowler has tallied 553 career tackles in his nine NFL seasons, contributing 59 tackles, one interception and a defensive touchdown this season during the Patriots' 13–5 run en route to an AFC Championship and a spot in Super Bowl LIII in Atlanta.
Jason McCourty will become a free agent after the season, while Devin has one year remaining on his contract. Whether or not either decides to play in 2019 is still to be determined.
The McCourty twins and the rest of the Patriots will face the Rams on Sunday, Feb. 3. Kickoff is set for 6:30 p.m. ET.
