Christian McCaffrey to see specialist in Germany for Achilles tendonitis

Eighteen days ago, we suddenly learned that 49ers running back Christian McCaffrey’s calf strain included an Achilles tendon problem. Two weeks ago, we suddenly learned that “questionable” meant “out.”

Tonight, ESPN.com’s Adam Schefter reports that McCaffrey see a specialist in Germany for his Achilles tendonitis.

McCaffrey was placed on injured reserve ahead of the Week 2 game against Minnesota. He is eligible to return for the Week 6 game on Thursday night at Seattle. Given that he is traveling across the Atlantic Ocean looking for answers to his lingering issue, it appears he won’t be back anytime soon.

Jordan Mason has had two games of 100-plus yards in McCaffrey’s absence. On Sunday in Los Angeles, Mason had 19 carries for 77 yards against the Rams. He also caught two passes for 11 yards.
