Jackson is believed to have suffered a high-ankle sprain in Thursday's win over the Giants, but he'll undergo an MRI on Friday before a determination is made on surgery, Adam Schefter of ESPN reports.

EDGE Analysis

The 33-year-old returned from a three-game absence and caught three passes for 34 yards and rushed once for 12 yards Thursday before suffering the injury while fielding a punt. A high-ankle sprain would likely sideline Jackson for at least the next few weeks, but he's apparently not out of the woods for potentially having an even more serious injury.
