Cleveland signed Froholdt on Tuesday, Nate Ulrich of the Akron Beacon Journal reports.
The Browns swiped Froholdt off the Texans' practice squad after placing backup center Nick Harris (hamstring) on injured reserve. Froholdt was drafted in fourth round of 2019 by New England and appeared in eight games for the Patriots in 2020 before landing with Houston. Harris must miss at least three games.
