Less than 24 hours after signing Chris Johnson to a two-year deal that might be worth as much as $9 million, ESPN's Adam Schefter reported that the Jets have some concerns over the condition of his knee. Johnson apparently has some arthritis in it stemming from his torn meniscus in 2013 (which he played through).
Johnson hasn't missed a game in five straight seasons. He's expected to form a one-two punch with Chris Ivory in the Jets' backfield this year.
