Stafford had X-rays on his left hand after Sunday's loss to the Vikings, the Detroit Free Press reports.
Stafford was able to finish the game and said afterward that his non-throwing hand should be okay. He got off to a fast start against the Vikings, but he was sacked seven times by the end of the day, ultimately finishing with 256 passing yards and a pair of touchdowns. The Lions have a Week 8 matchup with the Chiefs in London.
