He struggled with injury in the preseason lead-up and made the most of his opportunity on Saturday.
"It felt great," Allen told theRams.com. "I was so happy. I was telling my wife and my parents today just like, thank God, you know? I don't feel like I'm just in the back, I feel like I can contribute in some way. It felt good. I had a lot of frustration this past 3-4 weeks, and as a rookie, you want to prove yourself. And not being able to do that has been frustrating and scary, just because, you know the situation. It felt good just to let my frustration go a little bit, cut it loose and try to have as much fun as I could."
Allen was taken with the 175th overall pick in the fifth round of April's NFL draft.
After missing time due to a hamstring injury, Rams rookie tight end Davis Allen was happy to make the most of his preseason debut Saturday night against the Raiders.
