Contreras (hand) is out of the lineup for Tuesday's game against the Phillies, Chris Cotillo of MassLive.com reports.
Contreras had medical imaging come back negative after being hit by a pitch on the right hand Sunday against the Rays, and he'll be held out of Tuesday's starting nine after Monday's team off day. Per Jen McCaffrey of The Athletic, Contreras is improving and looks to have a good chance to return to action Wednesday. Mickey Gasper is stepping in at first base Tuesday for the Red Sox.
