‘Jones, the 6-foot-5-inch Ohio State product who was a fourth-round pick of the Bills in 2016, started and played the first half of a Defenders scrimmage last week. The 6-foot-7-inch Jackson, who went undrafted last year and spent training camp with the Bills last summer, played the entire second half. Jones lasted just one season on the Bills’ roster before spending 2017 and 2018 with the Chargers.’
