Pinkston started all 16 games for the Browns in 2011 as a rookie, thanks to an injury to fellow offensive lineman Eric Steinbach. Cleveland selected Pinkston with the No. 150 overall pick in the 2011 NFL Draft.
Pinkston first showed symptoms of his illness during Cleveland's game against the Cincinnati Bengals on Oct. 14. Days later, he was brought to the hospital.
Hopefully for Pinkston and his family, he is able to make a full recovery, and is able to resume his NFL career after the season.
John Greco started in Pinkston's spot against the Indianapolis Colts, and will likely remain the starter for the duration of the season.
