Clark has missed the last four games after injuring his lower left leg. Angerer went into last week's game at New England as the NFL leader in tackles but left with a right knee injury during the Colts' first defensive series.
Both were full participants at practice Friday. Coach Jim Caldwell says Clark is likely to play against the Ravens. Angerer is listed as questionable on the team's injury report.
Also Friday, Caldwell acknowledged that one of offensive coordinator Clyde Christensen's daughters went into labor during last Sunday's game. After the game, Caldwell says Christensen was relieved after the game to learn that mother and child were both healthy.
