Baltimore Ravens second-round linebacker Sergio Kindle is unlikely to play in 2010, head coach John Harbaugh said on Friday.

"He’s got some serious issues that he’s dealing with," Harbaugh said. "I think the chances of him playing this year are slim. We’re going to be very, very careful. The doctors will be very careful. Sergio will be very careful with that type of an injury."

Kindle is the lone unsigned member of the 2010 NFL Draft class. Harbaugh would like to get Kindle into the fold and have him around the team, but to do that, they'll need to get him under contract.

With Kindle's long-term playing future in doubt, that will require some creativity on the part of Ravens general manager Ozzie Newsome, VP of Football Administration Pat Moriarty, and Joel Segal, Kindle's agent.

"We’re dealing with the Management Council right now to try to work out the issues of the contract. That’ll be between Ozzie, the Management Council with the rules and Sergio’s agent. But we’re going to try to get him in here and make him a part of things," said Harbaugh.

"He wants to be here. He wants to be a part of things. He wants to get back on track. Then while we do that, (Kindle can) continue his physical therapy through the process and just see where that takes us."
