Colts QB Anthony Richardson exits in the first quarter against the Baltimore Ravens because of a finger injury after being sacked by David Ojabo. (0:27)BALTIMORE -- Indianapolis Colts quarterback Anthony Richardson Sr. had just been flattened by an unblocked defender when he looked down to secure the football. Coach Shane Steichen had planned to have Richardson play a majority of the first half Thursday as part of the team's evaluation of the two quarterbacks. Richardson said he thought the nickel corner might be the blitzing defender, but the Ravens "brought it from the other side." After the injury, Richardson tested his ability to grip and throw the ball and initially had difficulty.
