Turner and general manager A.J. Smith are expected to be fired because the Chargers (7-9) missed the playoffs for the third straight season. The Raiders finished 4-12.
If Turner does get fired, he'll finish 56-40 in six seasons with San Diego, but just 24-24 the last three seasons.
Turner's overall regular-season record as an NFL head coach is 114-122-1. He was 49-59-1 in Washington from 1994 until being fired with three games left in the 2000 season and 9-23 with Oakland, where he coached from 2004 until being fired after the 2005 season.
He was hired by the Chargers in February 2007 after Smith won a power struggle with Marty Schottenheimer.
Spurlock took the opening kickoff and ran up the middle of the field before cutting over to the right sideline to give the Chargers a lead they wouldn't give up.
He became the first Chargers player to have a kickoff and punt return for touchdowns in consecutive weeks. He returned a punt 63 yards for a touchdown a week earlier in a victory against the New York Jets.
Oakland quarterback Terrelle Pryor made his first career start, in place of injured Carson Palmer. Pryor threw his first career touchdown pass, a 9-yarder to Darrius Heyward-Bey early in the second quarter, and scored on a 3-yard run midway through the fourth quarter to pull the Raiders to 24-14.
Pryor's TD pass came two plays after Spikes and Goodson were ejected.
Goodson was blocking Spikes when the two locked up on a pass play in the second quarter. They remained locked up after the play ended and a larger scrum broke out.
Spikes and Goodson were flagged for personal fouls and ejected. Spikes had to be restrained by field judge Scott Edwards from going after referee John Parry.
As he was leaving the field, Spikes took off his helmet and flung it. Teammate Melvin Ingram caught it.
Backup tight end Randy McMichael walked Spikes off the field and the two hugged before Spikes disappeared up the tunnel.
After Oakland scored, San Diego took the ensuing kickoff and went on a long drive that resulted in Philip Rivers' 11-yard touchdown pass to Antonio Gates for a 17-7 lead with 2:48 left before halftime.
Pryor made some big mistakes.
With Sebastian Janikowski warming up on the sideline for a possible field goal attempt in the final seconds of the first half, Pryor scrambled but didn't get out of bounds and the clock ran out.
Early in the third quarter, Pryor got too much air under a pass and was picked off in the end zone by Quentin Jammer.
Rivers also threw a 34-yard scoring pass to Danario Alexander.
Rivers completed 13 of 17 passes for 151 yards and two touchdowns.
Pryor was 13 of 28 for 150 yards, with two TDs and one interception.
