Miller (head) will resume throwing Monday, Jack Harris of the Los Angeles Times reports.
Miller has been shut down and in concussion protocol after being hit in the head by a line drive during his first Cactus League appearance last week. However, he managed to avoid a serious injury and has been cleared to ramp his throwing back up. It's not clear when Miller might be ready for appear in a game again. Miller is likely to begin the season at Triple-A Oklahoma City.
