Ravens yet to place Dennis Pitta on IR (plus Spears and center battle)

Although the Ravens have repeatedly said tight end Dennis Pitta is out for the year with a dislocated hip, the team isn't yet ready to make that official.

Baltimore hasn't placed Pitta on season-ending injured reserve yet and on Tuesday, coach John Harbaugh addressed the lack of such a move.

"Well, it's not procedural. We'll put him on IR when we're certain that he's out for the year," Harbaugh said. "We know it's a serious injury, but when it came back that there was no ligament or cartilage damage, then that maybe gave us some hope. So we're going to wait and see how that bone heals over the first five weeks since the injury and see where we're at."

So could Pitta be back in 2013? Appears to remain a possibility.

Harbaugh also provided an update on Marcus Spears, saying the defensive lineman suffered a hamstring ailment. As for the severity of the injury, that is not yet known.

"It depends how it heals," Harbaugh said. "I expect him to be back pretty soon, but it's hard to put a timetable on it."

One of the most intriguing position battles of training camp is at center, between second-year lineman Gino Gradkowski and fifth-year lineman A.Q. Shipley.

Harbaugh and run game coordinator Juan Castillo both commented on the competition Tuesday.

"I would say it's a good competition. Those guys are both playing very well - that's what it is," Harbaugh said. "They're both playing really well, so that's a good thing for the Ravens. We'll just have to see how it plays out in the next couple weeks as far as who earns the starting spot."

Said Castillo: "Everybody says, 'Who's the guy?' We're talking to them and we need to have some separation. Somebody has to come to the top. The problem is that they're both playing really well right now. They're both doing a good job. In the pass protection, they're both using their hands really well and they're both good leaders. You guys have seen that on the field that they're both tough and ready to fight. They're really doing a good job. We're going to just ... The games are very important. Gino started last week with Joe (Flacco). This week, A.Q. will do that. Probably in the third game we'll split them up, and then we'll make a decision."
