Allen (neck/finger) was listed as a full participant on Wednesday's estimated injury report.
Allen had some soreness in his neck after Sunday's 27-21 win over the Patriots, but his full participation in Wednesday's walkthrough suggests he isn't in danger of sitting out this weekend's regular-season finale in Miami. His presence under center Sunday will be pivotal, as the Bills would win the AFC East with a victory but could miss the postseason altogether with a loss, depending on how things unfold in other Week 18 games. Since the Bills and Dolphins will kick off at 8:20 p.m. ET in the final game of the regular season, Buffalo will already know where it stands in the playoff picture before the game begins.
