Practice report - gray jerseys?

I haven’t been following the spring drill reports closely, what’s the deal with the grey jerseys?

See LJS practice report 4/4/23

They use the gray jerseys when a guy is playing multiple positions and moving back and forth between offense and defense

Thanks, Don, I thought it might be something like that.

Interesting that the portion of the practice the media got to see dealt with special teams, which have been a real sore spot the last few years.
