SAN DIEGO -- Thoughts from the San Diego Chargers' 16-13 overtime loss to the Baltimore Ravens.

What it means: The Chargers lost another close one, squandering a 10-point lead in the fourth quarter. How many more crushing losses can this team take? San Diego is now 4-7 and two games out of the wild-card race.

Defense falters late: The San Diego defense was great for much of the game. But Baltimore made critical third and fourth-down conversions late in the game. The Ravens scored the game’s final 13 points, and it was just another late collapse by the Chargers.

Fourth and 29: The play of the game was a fourth-and-29 conversion on a short pass from Joe Flacco to Ray Rice with 1:37 to go in regulation. It set up Baltimore's game-tying field goal at the end of regulation.

No Rivers miscues: Philip Rivers did not commit a turnover Sunday. He has a league-leading 43 since the start of last season.

Under pressure: Baltimore had six sacks and San Diego had five. The quarterbacks were under constant duress.

Defense gets banged up: San Diego linebacker Donald Butler and safeties Eric Weddle, Atari Bigby and Darrell Stuckey were all hurt. There is no initial word on the severity of any of the injuries.

Alexander looks good again: San Diego receiver Danario Alexander continues to sparkle. He had five catches for 74 yards. He may have a future with the team. Big-money free agent pickup Robert Meachem did not play as his role in the offense has bottomed out.

Wildcat works: The Chargers dusted off the Wildcat in the fourth quarter as Ronnie Brown, a Wildcat original, took a direct snap and went 13 yards on a third down and seven. It setup a field goal to give San Diego a 13-3 lead.

Slow going: Ryan Mathews led the Chargers with 72 yards on 19 carries. The Chargers do not have a 100-yard rusher in a game this season.

What’s next: The Chargers host the Cincinnati Bengals on Sunday. The Bengals have won three straight games and are very much in the playoff hunt.
