The Carolina Panthers are "cautiously optimistic" over the fitness of quarterback Cam Newton, who sustained an injury on Thursday.
Newton left the Panthers' game against the New England Patriots with a foot injury, and underwent further tests on Friday to ascertain the extent of the issue.
The 30-year-old had also undergone an x-ray on Thursday, with those scans coming back clean.
Panthers' general manager Marty Hurney offered a further update on Friday, describing Newton's injury as a "mid-foot sprain".
"Cam Newton has a mid-foot sprain in his left foot, and we are cautiously optimistic he will be ready for week one," Hurney said, as reported by The Athletic.
Even though the Panthers are cautiously optimistic, there has to be concern about how quickly Newton, who was sacked twice by the Patriors, can be back to 100 per cent fitness.
Speculation has mounted over whether the Panthers could make a move for Colin Kaepernick, who has been without a team since opting out of his contract with the San Francisco 49ers in 2017.
