The goal for Allen is to "manage" the injury without missing a game, per the report, including Week 10 against the Minnesota Vikings.
The Bills practice Wednesday, when coach Sean McDermott could discuss the short-term plan at the position. Veteran Case Keenum would be in line to start against one of his former teams in Minnesota if Allen rests this week.
Allen said Sunday night he felt "slight pain" in what he described as a bruise on his throwing elbow, an injury incurred in the Bills' loss to the New York Jets.
McDermott said Monday afternoon that a clearer picture of the injury would be gleaned by the Bills' medical team in the next 24 hours, creating some doubt about Allen's availability.
