Runners Get Credit, Too

"He should be fine," Harbaugh said. "It's just a matter of the head clearing up."

Mason: I caught it

Derrick Mason thinks quarterback Joe Flacco should have finished the day with four touchdowns, not three.

The wide receiver insisted that he held a pass thrown to him in the back of the end zone on the offense's opening drive. But officials ruled that Mason bobbled the ball before stepping out of bounds.

"Yeah, I'm a receiver, so I'm always hoping it's a touchdown," said Mason, who motioned to Harbaugh to challenge the ruling. "I thought I got my feet down, but you know, the coaches saw something else."

Harbaugh respectfully disagreed, saying: "You could see that his knee came down out. At that point in time, you don't want to waste" a challenge.

Multi-tasking

The offense sent its running backs out wide, and even quarterback Troy Smith lined up in the slot in the first quarter. Harbaugh said fans could see more of that in the future.

"Troy's a pretty good athlete out there, so they've got to match up with him, as well," Harbaugh said. "So we want to use all of our guys any way we can."

End zone

Harbaugh said tight end L.J. Smith could play Sunday. "There's a chance," Harbaugh said. "I don't know what the chances are, but there's a chance. We were kind of targeting this one. We'll be hopeful, but you can't say for sure." ... The Ravens held a short practice Monday but couldn't review game film because Sunday's opponent, the Chargers, didn't play until Monday night.
