While the return was a good sign for Johnson, his status is up in the air for the first preseason game.
Andre Johnson took about 20 reps today. Gary Kubiak said Johnson looked good but doesn't know if he'll play Sat at CAR— Nick Scurfield (@NickScurfield) August 6, 2012
Johnson had been sidelined with a groin injury, while a lower leg injury kept Brown out and a hamstring injury held out Jackson. Brown was able to participate fully, while Johnson and Jackson were on a play count.
None of the three injuries figure to jeopardize their status for the start of the season.
