Calvin Johnson to be a game-time decision vs. Falcons

Detroit Lions wide receiver Calvin Johnson participated in practice Friday and will be a true game-time decision for Sunday's game vs. the Atlanta Falcons in London, England.

Johnson has missed the last two games with a sprained ankle and was a shell of his usual self in two games prior in which he played through the injury. 

The Lions' official website reports Johnson looked better at practice Friday than he did all week, earning the star wideout a questionable designation on the official injury report.

Johnson's status will have a big impact on fantasy football. The Lions and Falcons kick off at 9:30 a.m. ET, forcing fantasy owners in North America (and particularly those on the West Coast) to set their alarms to wake up and check if Johnson is active.
