Stevenson headed to the locker room during Sunday's game against the Packers to be evaluated for an unspecified issue, Mike Reiss of ESPN.com reports.
Before that, Stevenson carried six times for 32 yards and caught three of his four targets for 46 yards and a TD. With TreVeyon Henderson (illness) sidelined for an undetermined amount of time, Corey Kiner and Lan Larison are available to handle New England's backfield duties Sunday as long as Stevenson is out of the game.
