Houston Texans wide receiver Andre Johnson left Sunday's practice with a slight groin injury, according to Coach Gary Kubiak.
Johnson was taken out as a precaution, according to John McClain of the Houston Chronicle.
The Texans are relying heavily on Johnson as they don't have much experience beyond him and their other starter, Kevin Walter.
UPDATE: The Texans say Johnson could miss about a week as he recovers from the groin strain.
