CINCINNATI -- Bengals head coach Marvin Lewis says his health break took only a few hours before he was back at work Tuesday night.
"I was able to return to work last night after receiving great medical care," Lewis said in a statement from the club Wednesday morning. "I especially want to thank all of the doctors, nurses and technicians who treated me. I am glad to be back with the team as we prepare to play the Buccaneers on Friday.”
The Bengals had said Lewis, 58, left the team Tuesday afternoon "to focus on a minor health issue," which the team did not disclose.
Bengals.com reported that Lewis was dealing with severe swelling in his knee. Stacy Deals of NFL Network reported that Lewis had a Baker's cyst. That's a fluid-filled cyst that causes a bulge and a feeling of tightness behind your knee, according to the Mayo Clinic. Both reports were unconfirmed.
Lewis used a cart to shuttle to the practice field earlier this week, which isn't his usual routine.
Special Teams Coordinator Darrin Simmons directed the team while Lewis was absent.
The Bengals host Tampa Bay in their preseason opener Friday night at Paul Brown Stadium.
