Ward, who was placed on the 10-day injured list Sunday, had been taken to a Toronto hospital for testing after being struck by a 91 mph pitch from Blue Jays right-hander Alek Manoah in the fifth inning. The ball appeared to strike Ward next to his left eye, knocking off his batting helmet and sending blood running down his face.
Ward was released from the hospital Saturday night.
Before Sunday's game, Angels manager Phil Nevin said Ward did not have vision damage. Surgery is an option for Ward, but no decision has been made. It was not clear when Ward would be able to return to California. The Angels play a three-game series at Atlanta this week before returning home Thursday to host Seattle.
It was the second hit batter of the game for Manoah, who hit Angels superstar Shohei Ohtani on the left foot in the first inning.
After the game, Manoah called it "a terrible moment."
"That's probably the worst feeling ever," Manoah said. "Definitely want to pray for him and his family. That's the last thing you want to do, no matter the situation, no matter the team, no matter anything. I feel really bad about it. I'll definitely be looking to see how he's doing."
Ward, a six-year veteran who has spent his entire career with the Angels, is batting .253 with 14 home runs and 47 RBIs in 97 games.
In a corresponding move, the Angels selected the contract of infielder Kevin Padlo. The 27-year-old Padlo has hit .125 in three games for the Angels this season.
