Panthers general manager Marty Hurney revealed that quarterback Cam Newton has a mid-foot sprain in his left foot.
Hurney also said the team is "cautiously optimistic" that Newton will be ready to play in Week 1 of the regular season. The 30-year-old signal-caller was seen heading to the team's bus in a walking boot following his preseason debut in the Panthers' 10–3 loss to the Patriots on Thursday night. He exited the game late in the first quarter after being sacked by Adam Butler and limping off the field. Sports Illustrated's Alber Breer reported on Thursday that Newton was diagnosed with a sprain in his left foot after getting x-rays.
