Foster downplayed the severity of the injury in a conversation with Gregg Doyel snd Will Brinson of CBS Sports.com on Tuesday and tweeted a picture of an MRI of his hamstring Wednesday.

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

Because this is what it does, ESPN had a doctor offer a diagnosis and prognosis: there’s bleeding in the leg and Foster may be sidelined 3-4 weeks, which is problematic with the Texans opening Sept. 11 opener against the Indianapolis Colts.

So ... clear as mud, right? When speculation about the injury burst into flames, Foster offered a clarifying tweet: “If I had a ‘significant injury’ why post it? I'll be fine, it was jus[t] meant to make fun of the whole situation. Humor is lost nowadays.”
