WASHINGTON (CBSDC/AP) — The National Football League is becoming family-friendly with its drug-testing.

Washington Redskins quarterback Kirk Cousins revealed on Twitter Tuesday that the NFL conducted a drug test for him at his grandmother’s house.

“NFL’s off-season drug testing at my grandma’s town-home!” Cousins tweeted. “I’m all for a clean game but weird having a stranger watch (you) in your own bathroom.”

Cousins, a rookie quarterback from Michigan State, backed up Robert Griffin III last season. Cousins performed well when called upon, throwing four touchdowns in three games and rallying the Redskins to an overtime win against the Baltimore Ravens after RGIII went down.

Cousins is expected to be the team’s starting quarterback going into the season if Griffin hasn’t fully recovered from surgery after tearing two knee ligaments in the Redskins playoff loss to the Seattle Seahawks.

Griffin says his surgically repaired right knee is improving and he will “be ready” to play, but has yet to set a timetable for when he does come back. Griffin led the team to the NFC East title last season and its first playoff appearance in five years.
