Buffalo Bills wide receiver Steve Johnson did not practice on Saturday due to a sore groin. His absence was merely a precaution but it is noteworthy that Johnson has had groin issues in the past. The injury first flared up again on Friday. Johnson had surgery on his groin in early May although it was described as an "extremely minor" operation at the time.
These sorts of injuries flare up easily and require rest for them to pass. The fact that he is mindful of it and caught it before it became serious is a good thing. Johnson has nothing to prove this offseason and should remain very high on your draft board. Look for him to be selected late in the sixth round in 12-team leagues. According to recent trends, his average draft position is on the decline, especially with the Bills lacking a strong WR2.
