LOS ANGELES — Red Sox first baseman Willson Contreras was held out of the lineup Saturday for precautionary reasons after being hit in the head by a 95 mph fastball on Friday night, but while he remains in concussion protocol the All-Star appears to have avoided serious injury.

Jarren Duran's dugout blowup over Willson Contreras not scoring adds to a long list of incidents as the MLB trade deadline approaches for Boston.

The trade for the 25-year-old second baseman shakes up the Red Sox batting order, alters playing time and affects roster construction.

A key Red Sox starter was a late scratch from Tuesday's lineup, though the catcher said he expects to be good to go by tomorrow.
