Coby Fleener is questionable for Sunday's game between the Indianapolis Colts and the Buffalo Bills, according to the Colts' official site. Fleener has not played since suffering a shoulder injury against the Tennessee Titans in Week 8.
Fleener was a limited participant in practice throughout the week, so it's unclear if he would play a full slate of snaps even if marked active. Dwayne Allen has played well as the Colts' full-time starter at tight end, with 14 receptions for 175 yards over the last three weeks.
Fantasy Impact: Fleener may very well play, but it's hard to imagine a scenario where he sees exclusive targets from the tight end spot. Allen has more than pulled his weight as a pass catcher, with a timeshare looking like the most positive outcome for Fleener owners.
Unless you are in a very deep league, Fleener should probably be kept out of your starting lineup, or off your roster altogether this week. Monitor his performance, and reconsider him for the Colts' Week 13 matchup against the Detroit Lions.
