Ravens offensive coordinator Marc Trestman on Thursday said Jimmy Clausen "played very well under the circumstances" in his debut against the Seattle Seahawks, and updated the status of his three quarterbacks: Clausen, Matt Schaub and Ryan Mallett.
"I thought he threw the ball exceptionally well," Trestman said. "He admittedly missed five or six throws that could have arguably allowed us to continue drives, make some plays. We didn't score, obviously. That's not good. But his play, first time out, he did a lot of good things and had a good communication on the sideline with our players, with his receivers, and did an admirable job."
Clausen threw for a career-high 274 yards, completing 58 percent of his passes with no touchdowns and an interception Sunday in a 35-6 loss to Seattle, and has taken "at least 50 percent of the practice time this week," Trestman said.
Most of the rest have gone to Schaub, who was limited in practice Wednesday and looked to be laboring physically and struggling with his accuracy during the open portion of practice Thursday.
Trestman said it will be up to coach John Harbaugh, the team's medical staff, and Schaub to decide whether he can play. Harbaugh said if he's healthy enough to play, he will start.
"We'll see where we are tomorrow," Trestman said. "He's still a little bit sore and he did get work, and he threw the ball effectively. He'll just have to see."
The practices this week have also included six-to-12 plays for new quarterback Ryan Mallett, who has made a "really good first impression" on Trestman and would presumably back up Clausen if Schaub can't play Sunday.
"I think that what's impressed me more is just sitting down and talking to him, he's taking this very seriously," Trestman said. "He's been here 24/7 the last three days doing everything he can to soak up as much of the offense as he can. What's impressed me most is, we all see his assets, his physical ability, but he's got football intelligence. He's picked up some verbiage very quickly. We've thrown him in there in practice."
