Twitter 2, Arian Foster 0.

The running back has taken it upon himself to update the world and the NFL about his hamstring injury.

Foster tweeted: "This is an MRI of my hamstring, The white stuff surrounding the muscle is known in the medical world as anti-awesomeness."

Attached with his tweet was a picture of his MRI, showing the extent of the damage done to his left hamstring.

Foster left during the first quarter of the Texans preseason game against the San Francisco 49ers on Aug. 27 after aggravating the injury, which occurred earlier in training camp.

Foster's tweet proved that his injury was more severe than previously described by Foster and Texans coach Gary Kubiak. ESPN’s medical expert stated, "a return to the field would not be expected before three or four weeks," and a premature return would only further exacerbate the injury.

After reports of Foster’s tweet hit the press, the running back tweeted again that the injury was still only a mild strain.

"If I had a 'significant injury' why post it? I'll be fine, it was jus (sic) meant to make fun of the whole situation. Humor is lost nowadays," he tweeted.

Backpedaling aside, the damage has been done. His declaration has not only made him more susceptible to possible targeted hits to the hamstring when he returns to the field, but also a measurable decline in his fantasy value.  

The Texans organization responded Wednesday.

"We are aware that Arian tweeted a picture of his MRI," general manager Rick Smith said in a statement. "It's a violation of team policy to disclose medical information via social media and he is aware of that. We will handle this situation internally."
