Wings center Luke Glendening, who lived with Callahan, Sproul and Riley Sheahan in Grand Rapids, was concerned when he heard about the incident.
"I called him last night, just to see what happened, to make sure he was doing OK," Glendening said. "He was on the phone, a little hard to understand, but that's understandable with what happened."
Unlike many people who saw the photo, Glendening was actually relieved to see Callahan.
"If I would have heard what happened and didn't see his picture I probably would have been a little more nervous," Glendening said. "I guess to see the picture gave me a bit of relief to know that he was OK."
Glendening thought it was amusing that Callahan put the picture out on social media.
"Guys have done that with cuts and injuries before," Glendening said. "I thought it was pretty funny."
Maybe Sproul is the one who needs the reassuring phone call from Glendening.
On his Twitter account, @Sproully93, he said, "Not a fun time when my friend and roomie goes down like that. Terrible feeling & hope he's back asap. Love ya Darrel #dinneronme @Mcally15."
