Johnson (knee) will be a limited participant in Tuesday's practice, Jay Skurski of The Buffalo News reports.
Johnson was forced out of Sunday's 34-28 win over the Cardinals due to the knee injury, though his ability to practice in some fashion two days later suggests he's not dealing with a major injury. However, with the Bills facing a quick turnaround for Week 2 with a Thursday night game against the Dolphins, it's unclear if Johnson will heal quickly enough to make himself available. If Johnson is inactive Thursday, rookie Ray Davis could notice a slight uptick in snaps as the clear No. 2 option behind lead back James Cook.
