England prop Andrew Sheridan is almost certain to miss the rest of the Six Nations after suffering a torn calf muscle in 17-9 win over France, and leaving Twickenham on crutches.
“He has got a tear in his calf which is not great,” Johnson said. “It probably takes him out for the remainder of the series.”
On Toby Flood he added: “Toby has been scanned and he is pretty good, just a little bit of soreness in his Achilles, so that was a relief,” Johnson added. “Flood is okay. He has a bit of Achilles tendon soreness. We think he will be fine, but we will be very cautious with him this week,”
