CeeDee Lamb is issued a penalty after a referee barrels into him on the sideline. (0:25)Open Extended ReactionsINGLEWOOD, Calif. -- Dallas Cowboys wide receiver CeeDee Lamb did not play in Saturday's 31-21 preseason loss to the Los Angeles Rams, but he took one of the bigger hits of the game. They said he's OK, the official that he ran into, but we have to be better than that," Cowboys coach Brian Schottenheimer said. The Cowboys were flagged 15 yards for unsportsmanlike conduct, and the Rams were also flagged for pass interference. "It's something that everybody is aware of, that white area is our area to work safely," Moore said.
