FILE - In this Aug. 8, 2019, file photo, Buffalo Bills defensive tackle Ed Oliver (91) plays during the first half of an NFL preseason football game against the Indianapolis Colts in Orchard Park, N.Y. If the Buffalo Bills drafted Oliver with the expectation to replace Kyle Williams at defensive tackle, who better than having the just-retired player pop in at training camp and provide the rookie a weeklong crash course. Oliver happily referred to Williams as being his "cheat code" to the NFL. (AP Photo/Adrian Kraus, File)

FILE - In this Jan. 7, 2018, file photo, Jacksonville Jaguars running back Leonard Fournette (27) makes a reception over Buffalo Bills defensive back Leonard Johnson in the second half of an NFL wild-card playoff football game in Jacksonville, Fla. Fournette missed seven full games and half of two others with hamstring and foot injuries. He was suspended for another after coming off the bench and punching Buffalo defensive lineman Shaq Lawson. What Fournette does will go a long way toward determining whether the Jaguars remain at the bottom of the AFC South or return to being conference contenders. (AP Photo/Stephen B. Morton)
