LB Smith injured

SANTA CLARA, Calif. — The San Francisco 49ers are concerned linebacker Malcolm Smith, one of the team’s most coveted additions in free agency, might have suffered a significant injury Saturday during practice inside Levi’s Stadium.

Smith, 28, left the field during fullteam drills with an apparent upper body injury after working with the starters throughout training camp next to All-Pro NaVorro Bowman in the new-look defense.

“We think it was his chest area. Don’t know for sure. But that’s what it looked like,” 49ers Coach Kyle Shanahan said.

Smith, the MVP of Seattle’s Super Bowl-winning team in the 2013 season, was brought in by San Francisco on a five-year contract in March.
