Allen has been diagnosed with a fractured foot and will be listed as doubtful for Sunday's NFC championship game against the Cardinals, Joe Person of the Charlotte Observer reports.

EDGE Analysis

Allen sustained the injury during Sunday's divisional-round victory versus the Seahawks, and subsequent examinations confirmed its extent. While the Panthers will take the healing process day by day, head coach Ron Rivera is unsure whether or not Allen will require surgery. However, Wes Horton is the prime candidate to be promoted from the practice squad, if Allen is unable to recover in time for Sunday's contest.
