Saw this on rotoworld per mando. Hope he passes all the tests, we need all hands on deck this week.

A "source close" to Lamar Miller tells the Miami Herald his concussion isn't "too serious."
Miller got in some work in Tuesday's practice, though it's unclear how much. Either way, it's an excellent sign for his Week 15 prospects. The Dolphins will officially update Miller's status on Wednesday.
