IRVING -- Cowboys backup tight end Martellus Bennett suffered a muscle strain in the rib cage area in the first half of Sunday's loss to Arizona.
Bennett said he underwent a X-ray at Sundays' game and a CT-Scan Monday.
Bennett said he's not sure if he'll practice this week or even play in Sunday night's game vs. the New York Giants.
If Bennett is unable to play, the Cowboys might keep two fullbacks on the game-day roster with Tony Fiammetta's expected return for the Giants game. Shaun Chapas was moved up from the practice squad last week to the 53-man roster with Fiammetta out.
