Allen agreed Wednesday with the Texans on a one-year deal, Nicki Jhabvala of The Washington Post reports.
According to Jhabvala, Allen's deal is for $2.5 million and includes $2.25 million fully guaranteed. The 26-year-old -- who spent the last two seasons with Washington -- will provide Houston with added quarterback depth behind Davis Mills, the team's projected starter for 2022 with Deshaun Watson expected to be traded this offseason.
