"I felt sick to my stomach," Patrice Bergeron said.
"The whole room was pretty shaken," Chris Kelly said.
"Right away you just want to make sure he's OK," Shawn Thornton said. "That's the initial reaction. You have a terrible feeling in your gut and just hope that he's OK."
The Bruins sent scores of text messages to Peverley and Tyler Seguin, just hoping to get some news on the situation, which they had found about on Twitter.
"I shot a bunch of texts to everybody," Thornton said. "Actually Segs called me right back and gave us the 411.
"You never want to see that obviously, but he's one of our good friends on this team. He's one of the great guys. We were pretty worried. The room went pretty quiet, but he texted me back today though and I think he seems to be doing OK. That's a positive."
Peverley spent today undergoing tests to determine the reasons for the collapse, according to reports out of Dallas. Stars general manager Jim Nill said that Peverley was in stable condition after the incident.
"It was good to hear at least that he was feeling OK and he was stable," Bergeron said. "But with that being said, thoughts and prayers are with him and his family. And I'll send lots of positive energy, also."
