Jones did not participate in practice Tuesday due to an undisclosed injury, Mike Rodak of ESPN.com reports.
Jones has been healthy all offseason, so it's unclear exactly what his him sidelined. The Bills don't appear to be overly concerned with Jones' health, however, so this may just be precautionary at this point in the offseason. With Cole Beasley (abdomen) still out, the Bills will be without two of their top receiving options to kick off this week of practice.
