INDIANAPOLIS -- Raiders head coach Jack Del Rio, a Hayward native, would like to see a Bay Area tradition renewed.

Today, Del Rio said he’s hopeful the Raiders will meet the 49ers in the preseason this summer for the first time since 2011, when fan-on-fan violence marred an exhibition game at Candlestick Park. The Raiders and 49ers did play a regular-season game in 2014 in Oakland without incident.

Del Rio also expressed an interest in having joint training-camp practices with the 49ers in August.

The 49ers and Raiders had met annually since 1967 before the series was halted six years ago.

As a result, both teams have often traveled long distances for preseason games rather than remaining in the Bay Area. Last year, the Raiders visited Green Bay. The 49ers, who have had joint practices with the Broncos the past two seasons, traveled to Houston in 2015.
