Running back Jahmyr Gibbs refuses to spill the beans too much after missing practice again during his contract talks with the Lions. With training camp underway, all eyes are on Jahmyr Gibbs, as he hasn't been practicing with the Detroit Lions lately. While there is speculation that the 24-year-0ld running back is holding in for a new contract, Gibbs' latest comments may suggest otherwise. “Lions RB Jahmyr Gibbs isn't practicing as he seeks a contract extension, but today, he spoke to reporters briefly coming off the field,” Pouncy wrote. Although Jahmyr Gibbs is in contract talks with the Lions, Detroit did pick up his fifth-year option.
