(AP) Miami Dolphins cornerback Xavien Howard has had surgery on his left knee that raises anew questions about his long-term health.
The fourth-year pro has had at least two other knee operations and at least one on each knee.
Despite his issues in the past, the Dolphins signed him to a $76.5 million, five-year contract in May. It was the most lucrative deal ever for a cornerback.
Coach Brian Flores is declining to discuss the nature of the latest surgery and will not say whether he expects Howard to be ready for the offseason program.
