The Columbus Lions signed quarterback Danny O'Brien, the team announced Wednesday.
O'Brien was the ACC Rooke of the Year as a freshman at Maryland in 2010.
After being redshirted, O'Brien took over the starting role in the fourth game of the 2010 season. He led the Terrapins to a 9-4 record by throwing for 2,438 yards and 22 touchdowns.
O'Brien was also named to the Football Writers Association of America freshman all-America team.
He played one more season at Maryland before transferring to Wisconsin for his junior year, then Catawba for his senior year.
After he was not selected in the NFL draft earlier this month, he was invited to the Atlanta Falcons' rookie mini-camp.
O'Brien joins Chris McCoy as the quarterbacks for the Lions. Antwon Young tore his ACL earlier this season and is done for the year.
McCoy started last week -- a loss at Nashville -- for the first time since the end of the 2011 season.
The Lions start a three-game homestand on Saturday night with a game against Lehigh Valley.
