Lewan was limited in practice on Wednesday but spent extensive time working one-on-one with coach Mike Vrabel during the open period of practice, jokingly telling Vrabel, a former NFL outside linebacker, he's lost a step.
Lewan met with an independent physician and was cleared after being a full participant in practice on Thursday. He was also a full participant on Friday.
"Taylor is ready to go. He's cleared and will be playing again. Anybody that we can get back is a boost," Vrabel said.
Added Lewan, "I feel good. I wouldn't have passed the protocol if I didn't. I have a wife and kid. I don't want to be that guy who is 45 years old and don't know my name."
Lewan may not be the only player returning to the field for Tennessee this weekend. Quarterback Marcus Mariota has made progress this week and had what offensive coordinator Matt LaFleur called his best day of practice on Thursday. Mariota continued to wear a modified glove that had the index and middle fingers cut out of it to help him grip the football.
Vrabel said Mariota will be listed as questionable for Sunday's game but said he will be cautious not to put his quarterback out there if he can't protect himself.
