Football practices at which middle- and high-school students tackle each other will be restricted in California under a law signed on Monday by Democratic Governor Jerry Brown, the latest U.S. effort to minimize brain injuries from the popular sport.
The measure, which limits practices with full-on tackling during the playing season and prohibits them during most of the off-season, comes amid growing concern nationwide over brain damage that can result from concussions among student as well as professional athletes.
