How long is A.J. Brown out? Injury update, return date for Patriots WR

The New England Patriots were on the wrong side of a 13-10 season-opening defeat to the Seattle Seahawks, but that may not have been the loss with the biggest impact on the rest of their season.

Wide receiver A.J. Brown, who was acquired via a trade with the Philadelphia Eagles in June, exited 90 seconds into the second half of the contest with a right ankle injury, as the Patriots led 7-0.

Before he left the game, Brown had three catches for 26 yards on four targets. He also helped draw a 34-yard pass interference flag on a flea-flicker play that set up New England's lone touchdown.

A.J. Brown injury update

Brown was initially ruled questionable to return. The 28-year-old stayed on the Lumen Field turf for a moment before walking off without his right cleat alongside the Patriots' training staff. After spending time on the bench, he went into the medical tent and eventually limped to the locker room.

Seahawks cornerback Nehemiah Pritchett appeared to land on the back of Brown's lower leg while defending a short slant intended for the wideout.

NFL Network reported that X-rays were negative and that Brown suffered a high-ankle sprain. He will undergo further imaging (MRI) to determine the extent of the damage.

"Running more tests," Patriots coach Mike Vrabel said Thursday, Sept. 10. "We'll update you here next week. Wasn't able to finish the game. Continue to evaluate. Continue to run tests. I don't know if he'll be available for the next week. I know that he'll do everything he can to get back as quickly as possible. Once we get the reports, we'll figure out what the treatment plan is."

Brown's injury timeline remains uncertain. Fellow wideout Romeo Doubs told reporters that Brown told his teammates "everything was going to be all right." The Boston Herald noted Brown exited the locker room while wearing a boot on his right foot.

The Patriots' next game is at home Sept. 20 against the Pittsburgh Steelers.
