It's been a long time coming for Trey Millard.
The former OU fullback experienced his first NFL game action on kickoff coverage for the San Francisco 49ers in Saturday's preseason game against the Houston Texans. Millard, who was picked by the 49ers in the seventh round of the 2014 NFL Draft, played in a game for the first time since tearing his ACL during his senior season at OU in Oct. 2013.
