Baltimore Ravens second-round linebacker Sergio Kindle is in stable condition after suffering a head injury during a fall at an Austin, Texas house, Jamison Hensley of the Baltimore Sun reports.

Henley adds that Kindle is believed to have fallen down two flights of stairs.

"Members of our medical staff, including Bill Tessendorf and Dr. Andy Tucker, have spoken with doctors in Texas. We understand Sergio is stable at this time and that he is being tested and observed," Ravens general manager Ozzie Newsome said.

Kindle, who remains unsigned, will not be present when the Ravens' rookie report to McDaniel College for training camp on Monday.
