Washington (CNN)Sen. John McCain received medical treatment for a minor tear to his right Achilles tendon suffered over the weekend, his office said in a statement Monday.

"Senator McCain was treated at Walter Reed Medical Center over the weekend for a minor tear in his right Achilles tendon, as well as for other normal and non-life-threatening side effects of cancer therapy," the statement read.
