A checkup revealed the clots in his legs and lungs.

"It was really alarming at first because I've experienced injury throughout my career, but it's never been anything like this that could turn into something detrimental if it's not taken care of," Goodwin said. "It was frightening at first, but now I'm at ease with it. 

"I've prayed and just given it over to God. It's out of my control, and the only thing I can control is my effort and attitude and how I approach each day moving forward."

Despite being sidelined, Goodwin will be around the team and in meetings.

"It's one of those things that is totally out of my control, out of the doctor's control and out of the trainer's control," he said. "It's really an unfortunate deal we have to deal with, but we need to deal with it in the proper fashion. The Browns are doing everything in their power to support me through it by allowing me to be around the team, on the field and in meetings.
