TENNESSEE TITANS (8-5) AT SAN FRANCISCO 49ERS (3-10)
KICKOFF: Sunday, 4:25 p.m. ET, Levi's Stadium. TV: CBS, Andrew Catalon, James Lofton.
SERIES HISTORY: 14th regular-season meeting. 49ers lead series, 8-5. The road team has won the last two head-to-heads, with San Francisco triumphing 31-17 at Tennessee in 2013 the last time they met. The Titans prevailed 34-27 in the most recent meeting in San Francisco in 2009. The series dates back to the year of the AFL-NFL merger (1970), when John Brodie threw three touchdown passes in a 30-20 49ers win at the Astrodome over the then-Houston Oilers.
KEYS TO THE GAME: The Titans, in a perfect world, would find a way to remedy Marcus Mariota's troubles on the fly. But that might be difficult to do, considering the team's wide receivers have had issues running routes, and Mariota's injuries have sometimes played a role in him not being able to consistently step into throws. That means the Titans need to get back to their bread-and-butter with the running game. Whether that is DeMarco Murray, Derrick Henry or some combination of the two, the Titans need to bounce back against a 49ers rushing defense that is in the bottom third of the league.
Defensively, the Titans have been doing well against bad quarterbacks in recent weeks. It will take a better effort to rattle Jimmy Garoppolo, who has led the 49ers to two straight wins since moving into the lineup. The Titans still need to put pressure on the young quarterback to get him out of his comfort zone.
The last time Garoppolo played at Levi's Stadium, he threw a last-play TD pass to finish off a loss to the Seattle Seahawks. This time he returns as an undefeated starter, after wins in Chicago and Houston.
"Getting these last two have been big for us," coach Kyle Shanahan said. "I hope that continues to lead us into playing better this week. The more you win, that's how you develop real confidence. And the more you win, players believe truly that they have a chance to win instead of just hoping. The more that happens, the easier it gets."
The two-game winning streak has been mostly a product of Robbie Gould's field goals -- he hit five to beat the Bears and four to help beat Houston.
If this game comes down to kicks, Gould could get the edge over Ryan Succop, who has missed at least one field goal in four of his last five games.
MATCHUPS TO WATCH:
--49ers QB Jimmy Garoppolo vs. Titans CB Adoree' Jackson. 49ers fans have seen the future in Garoppolo, but this provides a different perspective. If the club goes fishing for a superstar cornerback in the draft, plucking one similar to Jackson would be recommended. The former USC standout, drafted 18th overall by the Titans last April, has held his own on defense and been the club's chief returner.
--Titans TE Delanie Walker vs. 49ers S Eric Reed. You can bet Walker wants to do well against his old team. Since leaving San Fran for Tennessee, Walker has earned two Pro Bowl berths and become one of the best receiving tight ends in the NFL. Few, if any, tight ends have been more consistent this season than Walker, who has had between three and seven catches in all 13 games and has scored in two of his last three games.

PLAYER SPOTLIGHT: 49ers DE Elvis Dumervil. The veteran isn't exactly reliving his glory days, but his 5.5 sacks do lead the 49ers. None of the 5.5 came when the 49ers were continually frustrated by the Seahawks' scrambling Russell Wilson in their most recent home game. Dumervil basically pitched a shutout that day (no sacks, no tackles, just one assist) in 20 defensive snaps. The 49ers will need more from him against the Wilson-like Marcus Mariota.
