SANTA CLARA — Running back Christian McCaffrey has been dealing with issues with his Achilles tendons on both legs, 49ers coach Kyle Shanahan confirmed on Monday.
McCaffrey recently traveled to Germany to receive treatment for bilateral Achilles tendinitis.
“During the time, he’s had it in both (Achilles tendons),” Shanahan said on a conference call with reporters. “I think it started in one, (then) you overcompensate on the other. Mainly, one has been bothering him, but he’s had it in both.”

McCaffrey went through a week of practices in training camp before Shanahan disclosed on Aug. 6 that McCaffrey would be sidelined with a calf condition.
McCaffrey returned to practice one month later as the 49ers began preparations to face the New York Jets in the season opener.
However, McCaffrey was declared inactive for the first regular-season game. The conditions grew worse the following week as he continued to practice.
The 49ers placed McCaffrey on injured reserve on the eve of the team’s Week 2 game against the Minnesota Vikings.
