FILE - In this Sept. 17, 2017, file photo, Los Angeles Chargers running back Branden Oliver runs with the ball during the first half of the team's NFL football game against the Miami Dolphins in Carson, Calif. Oliver hasn't ruled out attempting a career comeback three years after various injuries derailed his NFL career. "I haven't fully retired yet. So I'm still waiting on the call," said Oliver, who spent four seasons with the San Diego-then-Los Angeles Chargers after completing his college career in Buffalo where he set the school record with 4,049 yards rushing. "And just watching him (Jaret Patterson) play has been motivating." (AP Photo/Mark J. Terrill. File)
