The Facts: Foster was carted off the field during Tuesday’s practice. According to John McClain of the Houston Chronicle, Foster had ice on his calf.

Diehards Line:In a follow-up tweet, McClain points out HC Gary Kubiak informed the media that Foster has a strained calf muscle. ... As PFT's Mike Florio notes, that’s good news, given that any time a guy is carted off the field with a lower leg injury, folks get anxious about how serious it could be. In Foster’s case, it’s apparently not serious at all. That said, we'll continue to follow up as further details come to light.
