UPDATE: The Patriots are placing A.J. Brown on IR. He will miss a minimum of four games.

New England Patriots wide receiver A.J. Brown suffered a right ankle injury during the third quarter of Wednesday's season opener against the Seattle Seahawks.

Brown required medical attention on the field before eventually getting to his feet and limping off. He went directly to the medical tent, and the Patriots officially listed him as questionable to return with an ankle injury. Brown was able to limp to the locker room for X-rays.

Pro Football Doc on A.J. Brown's Ankle Injury

Pro Football Doc said A.J. Brown's confirmed high ankle sprain will likely be measured in weeks rather than days, with an MRI needed to determine the severity of the injury.

A high ankle sprain involves the syndesmotic ligament and typically requires a longer recovery than a low ankle sprain. Brown left the stadium in a boot after suffering the injury.

“He's going to miss time,” Pro Football Doc said. “It will be lucky if A.J. Brown can avoid injured reserve designated for return.”

If Brown is placed on injured reserve, he would be eligible to return in Week 6. Pro Football Doc said there is still hope for an earlier return depending on the MRI results, but expects Brown to miss multiple weeks.

According to NFL Network, Pro Football Doc's video analysis was correct, Brown is believed to have suffered a high ankle sprain during Wednesday night’s loss to the Seahawks. X-rays were negative for a fracture, and he is scheduled to undergo an MRI Thursday to determine the severity of the injury and how much time he could miss.
