BALTIMORE (AP) — Police and fire officials say former Baltimore Ravens offensive tackle Orlando “Zeus” Brown has been found dead at his Baltimore home. He was 40.

The cause of death isn’t known.

Fire spokesman Battalion Chief Kevin Cartwright says firefighters were called about 11 a.m. Friday because Brown was unresponsive at his home near the Inner Harbor. Cartwright says Brown was dead when firefighters arrived.

Police spokesman Anthony Guglielmi (goog-lee-EL-mi) says firefighters called police, routine procedure in such cases. He said there were no signs of trauma or suspicious activity.

Brown began his career with the Cleveland Browns in 1993 and played twice for that team, as well as the Ravens, ending his NFL playing days in 2005. He started 119 of his 129 games.
