Rookie Joey Bosa will miss the San Diego Chargers season opener against the Kansas City Chiefs with a hamstring injury, general manager Tom Telesco told XTRA 1360 Fox Sports Radio.

“Obviously, we're not optimistic right now,” he said. “It truly is a day-to-day injury. It's a minor hamstring, and our goal is to make sure it doesn't turn into something long-term.”

Bosa recently signed a four-year contract to end a long holdout before the end of training camp.
