Coale, who is competing for one of the final wide receiver spots on the team, said his goal is to return for training camp that starts in late July.
"It's not what I wanted to happen," said Coale, who will wear a walking boot for a week to 10 days. "I see it as a minor setback."
Coale is not the first person in his family to suffer a broken toe. His brother broke his toe twice in college playing lacrosse and Coale's father did the same thing.
"I thought I was immune to it," Coale said.
The rookie receiver suffered the injury at the end of a conditioning drill when he planted his foot.
"I kind of knew it right away," he said. "It's not the best start, but it will be OK. I'd like to be out here getting reps. I'm taking it day-by-day right now."
"I'm going to try my hardest and focus on (getting healthy)," Coale said.
