Christian McCaffrey Questionable for 49ers' Opener Against Jets

The star running back is dealing with calf and Achilles issues but remains optimistic about playing.

McCaffrey missed four weeks of practice due to injuries but returned to limited practice this week.
Coach Kyle Shanahan has not confirmed if McCaffrey will play, listing him as a game-time decision.
The 49ers will also see the return of key players Trent Williams and Brandon Aiyuk after contract disputes.
Defensive end Yetur Gross-Matos and linebacker Dee Winters are ruled out for the game.
Safety Talanoa Hufanga is doubtful as he recovers from an ACL injury.
