ST. LOUIS (AP) — Michael Sam waited a while longer to get back on the field in his second preseason game.

When he did, he made a bigger impact in a bid to bolster his case for a spot on the St. Louis Rams' roster.

Sam, the NFL's first openly gay player drafted in the NFL, raced around tackle Derek Sherrod to flatten Green Bay quarterback Matt Flynn in the fourth quarter of the Rams' 21-7 loss to the Packers on Saturday for his first sack.

For Sam, the Southeastern Conference defensive player of the year with 11½ sacks for Missouri, it seemed like a long time coming.

"Finally. I finally got that under my belt, so it feels good," Sam said.
