Wise defensive back Marcus Allen, who orally committed to Penn State in May, is out for the season after tearing ligaments in his ankle, according to Pumas Coach DaLawn Parrish.

Allen suffered the injury when he, an Oxon Hill player, and one of his fellow Pumas defensive backs collided as Allen broke up a pass play early in the first quarter of Saturday’s 27-0 win over Oxon Hill. In the midst of the collision, the Oxon Hill player rolled over Allen’s ankle, which couldn’t withstand the blow.

The 6-2, 190 pounder had surgery Friday, and according to Parrish, Allen’s status with Penn State has not changed as a result of the injury.

The loss of Allen strikes another blow to the defending state champs, who suffered their first regular season loss since Oct. 2011 when DuVal beat them, 14-13, on Sept. 13, but who seemed to be rediscovering their swagger after their blowout of Oxon Hill last week. With Allen serving as a major deterrent to opponents’ passing games, the Pumas’ defense has allowed three offensive touchdowns in three games so far, a year after holding regular-season opposition to an average of three points per game in ten games.

In his painfully short senior season, Allen recorded 15 total tackles and recovered two fumbles. He made 69 total tackles with two interceptions, nine pass breakups and two forced fumbles in the Pumas’ 2012 state championship season.
