Left tackle Eugene Monroe excused himself from dinner with head coach Harbaugh Thursday night because he wanted to go upstairs at the team facility and spent more time studying the Ravens' offense.
It's been a crash course for Monroe, who the Ravens acquired from the Jacksonville Jaguars on Thursday for two draft picks. Monroe will eventually become the Ravens' starting left tackle, but Harbaugh said that he's still not sure the 26-year-old will know enough of the offense to play a prominent role Sunday.
"He seems good, he seems sharp," Harbaugh said. "He was here all night [Thursday] night with the offensive line guys. He was in here early this morning again and went through the practice and seemed like he knew what he was doing. I think we're on schedule, but I'm not sure what the schedule is with a guy like that. This is kind of new to us."
Harbaugh said that the team will partly rely on Monroe's feedback about his comfort level with the offense before making a decision. If Monroe is not ready, Bryant McKinnie will start at left tackle.
As his teammates worked through their final full practice of the week on another field, injured tight end Dennis Pitta stood about 10 yards away from the JUGS machine, catching ball after ball.
Pitta, who dislocated his right hip early in training camp and is currently on injured reserve with a designation to return, isn't eligible to play again until the Ravens' Nov. 3 against the Cleveland Browns, and a realistic target for his return is later than that. However, he continues to increase his activity, a positive sign for the Ravens, who have struggled to compensate for his absence.
"I'm pretty impressed," Harbaugh said. "He's running quite a bit in here on these machines, and he's already catching passes. That's a ways away time-wise. Every time I see Dennis, I got mixed emotions. I'm happy he's doing so well and I'm not happy that he's not already out there playing right now."
