Bullock — who nabbed an Oscar for her role as Oher’s no-nonsense adoptive mom Leigh Anne Tuohy — and her preschooler joined the football player’s family as they cheered him on from the stands.
And 3-year-old Louis — who was giving some serious game face — sported a mini version of Oher’s jersey.
“They stayed for the whole game and seemed to have a great time,” an eyewitness tells PEOPLE.
“Louis did watch some of it, but he also wandered around a bit. Sandra seemed very focused on the game. She was cheering loudly and acted very happy.”
At the end of the night, Bullock and her little sports fan had lots to celebrate. The Ravens defeated the San Francisco 49ers 34-31.
