After the Baltimore Ravens suffered a disappointing 26-23 loss to the Las Vegas Raiders on Sunday, veteran safety Eddie Jackson challenged the referees over a number of questionable penalties.

A defensive pass interference call on Ravens cornerback Brandon Stephens in the fourth quarter put the Raiders on the 1-yard line and allowed them to score a tying touchdown. Jackson lamented the call when speaking to reporters after the game.

“I’m not a referee or an official, but I feel like a couple of those calls were BS,” Jackson said. “In a situation like that, with the game on the line, that kind of call…”

In total, the Ravens were flagged 11 times, costing them 109 yards. The Raiders were given only three penalties for 15 yards.

After losing to the reigning Super Bowl champion Kansas City Chiefs in the season opener, Baltimore was expected to bounce back at home against Las Vegas. Unfortunately, the Ravens’ miscues allowed the Raiders to keep things tight before Daniel Carlson fired a go-ahead 38-yard field goal with 27 seconds left, handing the Ravens their second straight loss.

Baltimore will look to bounce back when it visits the Dallas Cowboys in Week 3.
