WATFORD, England – Calvin Johnson and LaAdrian Waddle were back at practice Thursday for the Detroit Lions.
Cornerback Rashean Mathis was absent from the open portion of practice due to an illness, but returned later on and was listed as a limited participant on Thursday’s practice report.
Mathis, who was evaluated for a brain injury during last weekend's loss to the Vikings and was cleared, was not listed on Wednesday's injury report. He has started every game for the Lions at right cornerback the last two seasons.
Johnson was given a non-injury related day off on Wednesday, but was back at it Thursday.
