"Just hearing what's happening with all these guys that played in the past and all the things that are popping up, it definitely scares you," he said. "So you have no choice but to let it (retirement) cross your mind. ... You don't really know what's going on in your brain. You just want to be extra cautious especially with that type of injury."
Smith didn't fly back with the Browns from Cincinnati, but was driven home the following day.
He had three catches for 30 yards against the Bengals before he was injured. The Browns missed his blocking the past few weeks, but they may need Smith back as a pass catcher this week with three wide receivers nicked up and uncertain.
Smith said it was frustrating not being able to contribute while he was out as the Browns dropped three straight games, extending their losing streak to 11 dating to last season. It was the Bengals who knocked him out and now he's coming back to face them again.
"That's fitting, huh?" he said. "Good time to come back. Hopefully we can get this win and make it all the better."
