Rivers: Allen back vs. Knicks
Allen has missed 10 of the team's last 15 games due to right ankle soreness. He did not travel for the back-to-back-to-back to open this four-game road trip, but will give it a go after a full week of rest (he last played in Miami on April 10).
The Celtics are 13-2 without Allen this season and 3-1 since he's moved to a bench role allowing second-year guard Avery Bradley to run with the first unit.
