Detroit Lions receiver Calvin Johnson has revealed that he will need rest and treatment to recover from a high right ankle sprain.
The 29-year-old suffered the injury against the Green Bay Packers last month and aggravated the issue on Sunday against the Buffalo Bills.
"Any time you're dealing with an ankle, you've got to run, you've got to cut, you've got to do all those things. It makes it tough. Just a lot of treatment that goes into it," Johnson said, ESPN reports.
"Takes some time to rest and get off your feet as well."
Lions coach Jim Caldwell conceded that he would strongly consider sitting Johnson this week in order to preserve his long-term health.
Johnson has 22 catches for 348 yards and two touchdowns in the five games that he has played in so far this season.
