St. Brown (quadricep) was a full participant in practice Wednesday.
St. Brown departed this past Sunday's loss to the Buccaneers in the waning moments due to a leg contusion and cramping. Head coach Dan Campbell told Richard Silva of The Detroit News on Monday that St. Brown "will be good," and the wide receiver's activity level to begin Week 3 prep supports that notion. St. Brown thus is on track to play Sunday at Arizona.
