The Lions lost receiver Calvin Johnson to a knee injury in the first quarter on Sunday. Pittsburgh defeated Detroit 28-20 at Ford Field. "We came into the game shorthanded and then got shorthanded early in the game with injuries," Lions coach Jim Schwartz told MLive.com. "He hurt his knee. We'll see where it is. He couldn't go back in and finish. We tried to get a sleeve on it, we tried to get a brace on it and it was a situation where it was still possible -- if he could feel good with it -- we would've put him back in the game. We couldn't get him settled down and we couldn't get him comfortable."
