Travel restrictions prevent Smith from seeing her son play in person until this weekend.
Thomas hopes his mother can see him play when the Broncos (12-4) host the Pittsburgh Steelers (11-6) on Sunday.
When his mother does attend a game, Thomas knows it will be an emotional event for all involved.
He told the Associated Press that the reunion "would mean a lot. This would be her first game. I'll be excited. She'll be excited."
