The 49ers released Thomas (hamstring) on Friday.
Thomas inked a one-year deal with San Francisco back in June and appeared set to provide the team with valuable veteran depth behind top tight end George Kittle, so it's somewhat surprising to see him be released two weeks into training camp. A hamstring injury had kept Thomas out of practice for roughly the last week, but unless he's reached an injury settlement, his release indicates a clean bill of health. Thomas will now look for an opportunity elsewhere in the league, likely as a backup or rotational option for another team.
